Depression

This is gonna be a long post, and I don't really care if anyone reads it or not. I just need to get it off my chest.. I'm 37 weeks pregnant. I'm depressed as fuck. My boyfriend and I have been fighting all day long. We're on the verge of breaking up. I have a shitty past. I was a slut in high school. We took a break and I hung out with other guys. He obviously thinks I've slept with all of them, because of my high school past. He's made it very clear that he will never marry me because of it and the fact of the people I hung out with when we were broken up. I've fucked my life up so bad because of my past. I've had to talk my self out of cutting myself all day long. The only reason I haven't is because of my baby.. I fuck up everything good I have in my life. He had a dream last night that I told him I slept with someone and he asked me about it this morning. I told him yeah, we hung out, but never did anything. Which we didnt. He tried but I made him stop and I went home. So because I never told him about us hanging out, he's mad. Like really mad. Idk I'm to the point of wanting to just end it all. My life, everything. The only thing keeping me from doing it, is my child. I feel like I have nothing else to live for. Like I said, I fuck up everything I have going for me in life, and it's very clear.. Idk just needed to get it out there
