cattle crowding

i printed off my boarding pass, and took the tiniest suitcase i could find ! despite this,having got through the security check in easy enough. the whole thing ground to a halt ! speedy boarding people were struggling to get through the crowd, and others were slipping through and then forced back into the queue. there appeared to be only one person trying to get the crowd through to board, and so we were stuck there for far too long. as a semi disabled passenger, i cant stand for ages, and felt really sick by the time i reached the plane. i had explained previously that i held a disabled card, but this didnt get me through any quicker. only when i got on the aircraft was there any reference to my needing help ! and because i also have a broken shoulder, it was a passenger !! who put my suitcase up on the locker.. what is the need for all this crowding when we are told that Gatwick is up and running, or is easyjets lack of staff that is causing the problems. not a comfortable journey up to Inverness at all.
