I'm depressed because my wife is divorcing me and I haven't seen my child in a while

I'm going through a divorce with my wife of three years, who I've known since the 4th grade and been involved with for seven years! We just had a baby seven months ago and never got along with my mother, who I've lived with for years. I am now back with my mother because I have nowhere to go with this divorce looming. I'm heart broken because I fell into a depression, I haven't seen my child in a while, I'm having good and bad dreams, and I feel hated. Can you help? Can you intervene? Can I speak with someone?
