is it normal

I'm almost 32 weeks pregnant falling into a depression. I have so much going on in my personal life the only way I could get away is by leaving my husband but I don't wanna bc it's not his fault. it's mainly his daughter n ex. and I feel if I leave it'll make me going into a depression more. I literally sleep all the time, I stay in my room n my bed not wanting to do a thing. what do I do? even if I were to leave I would have to go outta state which isn't a option.
