Feeling depressed

For 3 years now I thought I’d never be able to have kids due to PCOS and I recently found out we were 8 weeks pregnant (now 10 weeks). I was seriously considering a divorce due to lost feelings, being tired of taking care of a grown man after 5 years, dealing with mental and emotional abuse and out of nowhere we found out we were expecting. It’s not that I thought this pregnancy would fix anything, but the thing I thought would make me the happiest has not been what I thought it would be. I feel depressed, and alone. My husband has not supported me these past couple of weeks. He’s a selfish mamma’s boy and to be honest I don’t see him growing up anytime soon. He hasn’t worked in years, but says he will. He acts like anything I ask him to help with is going to kill him. I don’t know, I feel stuck.
