Morecambe boss Jim Bentley was "distraught" after seeing his side ship three goals to take just a point from a 3-3 draw at home to Rotherham.
The Shrimps raced into a 3-0 lead after just 37 minutes thanks to a third-minute opener from Gary McDonald and two Laurence Wilson penalties. But Rotherham hit back to claim an unlikely point thanks to Lewis Grabban's spot-kick and strikes from Gareth Evans and Alex Revell, before then coming closest to taking victory on a thrilling night at the Globe Arena.
Bentley said: "It was one of those games where you cannot really describe what has happened. We were brilliant in the first half and to get 3-0 up against a side as good as Rotherham was a dream start."
He added: "But from the minute they got a penalty of their own it was a totally different game. We made some individual mistakes and to give Rotherham credit they punished us for it.
"It's so hard to take but I have to take the positives from the performance. We have to look at the first half and take that as a marker and cut out the silly mistakes that we made in the second period.
"I am distraught and I think I will struggle to sleep because I'll be thinking about every kick of the game and how I can use the experience to make us stronger as a team and make me stronger as a manager."
Rotherham boss Andy Scott hailed his players for their superb fightback but insisted they have to stop rival teams opening up leads.
"To come from 3-0 down was fantastic and I have to give the lads a lot of credit for that at the end of the day," he said.
"But having said that we can't keep giving sides head starts like we are doing. We can't expect to score three goals every week to get points from football matches and it is something we have to sort out.
"We have a lot of very good players and a lot of very experienced players and they should be doing better than that. We defended far too high in the first half and played into Morecambe's hands and someone should have realised that. When we got back into the game we were by far the better side and if anyone was going to win it it was us."
