Broke off a keyboard ribbon cable

I made a big mistake opening the laptop. First of all I wanted to clean out the fan and repaste the system. Later I was able to remove the fan, but the rest of the cooler was just too hard for me to get off. Then I put the cooler back in and everything is okay… until i test the laptop. I put the keyboard back and plugged in the cables and the screen didn’t work. So I tried to remove the keyboard, but it cracked when I opened it. And then when i tried removing the cables, one of them broke. So I’m in a really bad situation, because any help is really missing for this laptop
