Depression while pregnant.

I am very ashamed to admit this but I have struggling really bad with depression and anxiety during this whole pregnancy. I've never had issues with depression before but I know for a fact that is what it is. I have been trying to fight it, convince myself that it's just pregnancy hormones but nothing is helping. I just want to cry constantly and I am so anxious about everything. I have "melt downs" almost every day. I feel like I can't control my emotions or actions at all. I know my husband must be at his wit's end. You have no idea how bad it has been. We wanted and tried for this baby for years, it should be a joyous time. I feel so guilty for feeling the way I do. I haven't spoken to my doctor about it because I keep hoping that it will get better and I guess I'm just too embarrassed about it but things seem to be getting worse. I have 9 more weeks of pregnancy, I can't imagine dealing with this for another 8 weeks. I feel like I'm dying inside! Anyone else deal with depression during pregnancy? Any suggestions??
