ABJECT misery for Town and bitter disappointment for their fans.
Those were the emotions as Peter Jackson's side blew it big style on their first ever visit to Huish Park.
Sloppily conceded goals to Terry Skiverton and Lee Johnson at the start of each half gave Peter Jackson nightmares and Yeovil just the spur they needed to chalk a fourth successive win.
It didn't help that the second came just as Town were looking to build on Jon Stead's equaliser, his 10th of the season, and threw their passing so far off the mark they could eventually have lost by more.
The small corps of travelling fans sloped off in disgust at the final whistle, sick at the thought of a second successive defeat and a slip to ninth place in the table after previously watching five wins on the trot.
A big improvement is needed against Carlisle at the McAlpine on Saturday and, judging by Jackson's face at the end and his decision to bring the players in for training today after a 500-mile round trip, Town will be determined to provide it.
Jackson complained for the first time this season about the desire of his team, but that wasn't the whole story.
For a large part of the first half, Town acquited themselves well in trying to bounce back from Skiverton's second-minute free header from a free-kick by the impressive Gavin Williams.
Andy Booth could twice have scored from close-range headers - the first on 25 minutes was the sort he normally eats for breakfast - and they had forced Yeovil deep into their own territory by the time Stead slammed in the equaliser from 22 yards out just four minutes before the break.
That made for a positive half-time team talk, but Town were quickly on the back foot again thanks to Johnson's diving header on 50 minutes and, this time, they couldn't recover.
Major reason for that was some diabolical passing.
In the first half, Town built attacks and pressure in the Yeovil half by finding Booth and Stead and supporting through accurate passing.
In the second, Town hardly strung two passes together and it meant that Yeovil could dominate in the centre and take control of the game.
Johnson - son of manager Gary - needed no second invitation, nor did the blond-haired workaholic Darren Way, one of three survivors from Yeovil's FA Trophy victory against Emley a couple of years ago.
They were all-action once Yeovil had their noses in front a second time and, in what seemed a conscious decision to put the ball behind Town's bedraggled back line, they created chances to seal the result beyond question.
Gray, who made a fine save from Kevin Gall on the break after Steve Yates had been stranded in the 22nd minute, had to be at his best to keep Town in the contest.
After being well positioned to stop a header from the 6ft 7in Portuguese Hugo Rodrigues in the 49th minute, Gray was twice left at the mercy of the Yeovil attack late on as his defence went AWOL.
Firstly, with 13 minutes left, Gall played a perfect pass over the top to leave substitue Kirk Jackson bearing down on goal, but his low drive lodged between the shins of the sprawling keeper, who was able to smother the following danger.
Then, in the final minute of normal time and with defenders nowhere to be seen, Gray saved with his feet again as Jackson looked to reward a crowd of 5,274 with another strike.
Town, in the sort of cave-in which cost them so dearly at Lincoln last Saturday, threatened only once in the second half before Jackson made a significant change.
Efe Sodje's downward header which bounced up and over the bar from Andy Holdsworth's right-wing corner was still fresh in the memory when, with 15 minutes left, Jackson sent on Nat Brown to replace centre-back Yates.
Brown played wide on the right in a new-look 4-4-2 formation - Chris Holland was already on for the first time this season in place of the out-of-sorts Lee Fowler - and Brown did well, forcing Yeovil to make a switch of their own to try and contain his threat.
Abdelhalim El Kholti and Colin Pluck each resorted to foul measures to keep Brown at bay and, as a result, Town created three reasonable opportunities to snatch an unlikely point.
Only seven minutes were left when Booth thought he had equalised.
Clarke caused the initial problem at a Tony Carss corner, but Sodje was flagged offside as he tried to follow up. It was only after Booth forced the ball home that fans noticed the flag, but the Town captain was still booked for his protests.
Two minutes after that and the hard-working Booth was in the thick of the action again, rising to meet a Carss free-kick at the back post and guiding his header narrowly wide to the dismay of the travelling support behind that open-end goal.
In the first minute of added time, too, Yeovil were relieved when Sodje broke free at the back post to tee up Clarke, but the teenager's header from six yards plopped harmlessly over the bar.
It was a demoralising finale to a below-par performance which leaves Town with plenty to think about before Carlisle visit on Saturday following their 4-1 home mauling by Scunthorpe last night.
Two defeats after a five-match winning run would suggest word is getting around the Third Division that Town can't be allowed to play.
Lincoln and Yeovil have proved that to their own advantage and now it's up to Town to respond against the country's bottom club.
Town Form (3-5-2)
Ian Gray Made excellent saves from Gall, Rodrigues and Jackson (twice) to keep Town in the game. Let down by defence Rating: 7/10
Andy Holdsworth Unable to make much impact going forward, especially in the first half. Supplied corner for Sodje to go close with header. Rating: 4/10
Tony Carss Some promising early attacks and worked hard throughout. Helped tee up Stead's goal from a free kick. Rating: 5/10
Nathan Clarke Caught in possession on a couple of notable occasions and his misdirected late free kick summed up the night. Rating: 4/10
Steve Yates Rescued by Gray when the pacy Gall got wrong side in the first half. Played some stray passes in the second. Rating: 4/10
Efe Sodje Not one of his better games, but his pace mopped up two dangerous Yeovil attacks. Close with a header. Rating: 4/10
Lee Fowler Played one superb cross for Booth which should have brought a goal but well down on his normal performance. Rating: 4/10
Jon Worthington Covered plenty of ground and was fouled in the move which led to Town's goal. Booked for virutally nothing. Rating: 5/10
Danny Schofield Supplied a great cross for Booth, a la Lincoln, but this time keeper Weale made a fine save. Didn't figure enough though. Rating: 4/10
Jon Stead Tried a couple of early efforts and struck his 10th goal of the season well. Saw no ball in second half. Rating: 5/10
Andy Booth Missed two good first half chances but worked hard across he line and held the ball as well as anyone. Rating: 6/10

Star Man: Ian Gray
Just pipped the hard working Andy Booth to the honour because, had it not been for his saves, Yeovil could have run away with it. Two second-half one-on-one saves from substitute Jackson when he was clean through stick out. Solid keeping.
Town gave themselves a mountain to climb with two badly defended goals at the start of each half, but Andy Booth missed the sort of heading chance he normally buries on 25 minutes and had another saved by Chris Weale.
