21 weeks and super depressed

21 weeks and constantly crying and depressive. Anyone could give me ideas on how to cope with a really bad break up after 3 years and a child on the way? I left everything I had to be with him, my apartment, lost my job because of my high risk pregnancy and scheduling conflicts. Now I'm left lost and have no idea how I'll make it through this, when I think I'm fine I find myself crying at night.
