Honestly scared to death!

I never really thought much of how I would feel about giving birth.. But now that I'm pregnant and don't have a choice it is seriously my biggest fear! Every time I think about it I get anxious about it and want to just cry! I never thought I'd be pregnant we went so long not trying but not using birth control that I just figured it wouldn't happen. Does anyone else get like this when thinking about birth? I hope I'm not the only one and someone can help me get over this fear because I'm so excited to have my baby!
