Fears?

I'm 32 weeks and I've having these fits of anxiety lately where I'm literally in tears thinking something is wrong with my little angel. I would love her either way I just know that if something were wrong it would be my fault because I wasn't strong enough to go through this pregnancy without medications. Now I'm refusing everything except my prenatals, but what if I'm too late? My husband prayed for us all today just to calm me down, and my mommy keeps saying its normal to be nervous. I guess my question is is anyone else out there doing this to themselves, too? And if so how are you calming your nerves?
