Pregnancy depression

Lately I have felt so alone, and for awhile baby daddy has been the only person who was there for me, and I don't have friends really, and the ones I do have are so busy with their lives right now, but I am so depressed, it's hard for me to even get out of bed, and I feel so alone, I have no idea what to do.. And lately I feel like he's so distant. I know he has his own life and his own friends, but they come number one to him, and it wouldn't bother me as bad, if I wasn't carrying his baby, and thus depressed. I know it's just the hormones but I have no one to talk to, is this a reason to be upset with him, or should I just sweep it aside.. Like I can tell him I need someone really bad and he'll say he's already made plans, but he's with them EVERY weekend..
