Depressed & Need Support.

I'm a 24 y/o FTM and I'm so scared and depressed at the moment. I'm 25 weeks pregnant with a heathy baby girl but I'm so down that I'm not happy with my current situation at all. My child's father isn't in the picture. I haven't seen him since January. He would much rather go on vacations and play house with his married gf (she has a husband). He doesn't offer me any kind of support. Just today I told him I was depressed because he isn't helping and he pretty much shrugged it off. My best friend all of a sudden became very distant when I told him I was pregnant and has pretty much ignored me too. I have the support of my mom and sister but I feel so alone it's hard to be happy. I try to give myself pep talks but it hurts. Just today I laid in bed and cried. I want to be happy but I'm hurting so bad 😔.
