Need advice

I'm 7 weeks 4 days with our second child. I'm anxious and depressed almost all of the time. I want to be happy and connected to my baby girl and to this pregnancy but I feel so lost. I love our daughter but I find myself so drained and I don't think I'm doing a good job with her. She's 10 months old and I barely get us out of the house. She deserves to be out and play and to be with other kids. And I just can't do it. How am I going to do what my babies need when I have a second one come may? I feel like a failure.

My situation is also complicated by my relationship with her father. I love him, we have been together for 4 years and come through a lot together. He's had a pretty steady drinking problem for the last couple years. I've lived with it because he doesn't get super drunk and he's still a good, loving man, but it's very hard for me to cope with it. I grew up with a mom who was a severe alcoholic so seeing him pick up a drink every night is killing me.

I'm contemplating trying to get myself and my daughter into housing. I'm just terrified because of how depressed I am that I'd never do it on my own. This should be such a happy time in my life but I feel as though I am drowning.
