Indescribable fear of child birth...

I really need advice or reassuring words... something.

I am 22 and currently carrying my first baby. My little boy is just about 36 weeks and I am stricken with fear about giving birth. I recently loss my mother just a few short months ago, it is probably one of the hardest things I have ever been through. Death seems to be a common obsessive thought in my daily life ever since I loss her. Especially when I think about giving birth. Thinking about my son not making it during the process or me bleeding out and my son being left without a mother are thoughts that are enough to keep up at night sometimes. I just have this indescribable gut feeling that something is going to go horribly wrong during my delivery. And the closer I get to my due date the more afraid I become. Of course I am absolutely excited to meet my son and he is well worth whatever may happen, but I just can’t let this feeling of worry go. I already tried talking to my OBGYN about my fears and she just brushed it off as normal pregnancy fears and that my body was made for this. I keep trying to remind myself of this but my thoughts always end up wandering to the worse.
