Why the hell wont she sleep

She turns five months next week. Past few nights she's been getting up like every half hour literally. It's almost ten pm and she's just in her crib wide awake playing and will soon get mad and scream. Idk wtf to do. I'm so exhausted I almost threw up and I want to scream at everybody I see. What the fuck am I doing wrong. I've tried fucking everythig. She keeps rolling over on her side and getting mad and waking up because she's rolled over. We even have her in the sleep suit and she just keeps rolling and getting mad. She won't sleep. Keeps pulling the pacifier out of her mouth, doesn't know how to put it back in, rolls over doesn't know how to roll back. Can't swaddle her because she's rolling. Can't do fucking anything. I honestly want to put a knife through my skull lmao. I'm such a terrible mother but I can't handle this :) :) :) :) :) and no one will help me either.
