Help dealing with postpartum depression

Im 6 weeks and 3 days along , ever since i found out i was extremely happy but ive also woke up and fell asleep crying everyday. My partner is in the army so its just me and my belly and i dont know how to deal with all the emotions i feel every hour. I get so mad and angry then i hate him then i sleep. I dont feel this stress is healthy for my baby , can someone please give me some tips on better ways to handle this?
