All the goals came in a hectic first 45 minutes when Orient left Carlisle reeling as they built up a commanding 4-1 lead. It was an x-rated showing from the Cumbrians' defence who contributed greatly to their own downfall.
A double from David Mooney and further goals by Lee Cook and Ben Chorley exposed major failings in the home rearguard although Peter Murphy did briefly bring the home side level..
Abbott said: "It's times like this when we have to stick together and dig deep. At the minute it's a tough situation and the facts are there to be seen and we have got to do something about it.
"The players have got to take some responsibility. They feel they have let the club, me and the supporters down. You have to take it on the chin and crack on and deal with it.
Abbott added: "We have managed the club in difficult times. We need our big players back and the senior players performing because the younger players did alright. It was the senior players I felt didn't do it well."
