Bf driving me insane

I lost my baby 12/22/14 and I am still missing him and I am still emotional. I'm mad he's gone, and I'm mad my boyfriend was such a pain in my ass the 4 months I was pregnant and I'm mad he is not leaving me alone now. I am not one to talk to a family member, or best friend even him at all when I'm emotional. I like to be alone, and try to find peace. He doesn't understand and he is making this whole process much harder for me. He wants to know everything I am thinking. I can not stand it. Idk what to do. I am not one to do what people say or ask and I feel he is asking too much.
