pregnancy and depression.

Pregnancy is supposed to be beautiful, I however am not having that experience that I once thought I would have. I'm very crabby and emotional and my boyfriend isn't handling it well, I've tried to be in a better mood, I've told him that I just want him to say nothing and hug me, to be careful with his words. But I feel like we are just constantly fighting ever since I got pregnant. I don't want to hinder him in anyway, I want him to live his life and not worry about me. I can't help but push him away and maybe it's because I secretly hope I'd die on a daily basis. I'm in my second trimester and I have no real job, I'm struggling, and I really just wish I had more friends and family to talk too. I wasn't really depressed when I wasn't pregnant and I don't know what to do. I'm stressed, exhausted 24/7, hungry 24/7, and I'm annoyed. Idk if I can do this, I'm not going to be a good mom.
