depression

i feel like i'm sinking into depression after giving birth... pregnancy was tough, high risk, hosp visits every 2 weeks, i was working ft and had a pt job, my husband didnt contribute much towards my appointments/ preparing for baby... he didnt even give me money for expenses. he MIA 2 weeks after i gave birth, came back home with tattoo, caught him cheating on me thrice as of now. want to divorce but he owes me $10k but fat hope of getting my money back lol. now he will call me "fucking dog" he likes to play victim. tells me he doesnt care about me. i wanted to kiss baby and he pulled and twisted my wrist that is already hurting from carrying baby a lot. punched my arms too. i hate him to the core. finding strength to walk away from this relationship.
