Extreme fear of labor

I am 19 weeks and I suffer from panic attacks and depression I have since I was 14 and I’m 38. I am terrified of labor. Part of what kept me from ever getting pregnant. Anything health related I panic. I’m scared when my legs go numb from epidural, or that if I can eat for hours my blood sugar will drop, or being exhausted or my high blood pressure going higher or my heart rate etc. when I get panic attacks it’s extreme. I vomit, poop, can’t breathe, shake, hot and cold. I am considering scheduled c section for this reason but I know that’s really rough and it’s a surgery. But I know if I’m in labor and start panicking they can’t give me like a Xanax. Anyone have insight or experience. I am so stressed out I don’t know what to do. It’s preventing me from enjoying my pregnancy.
