Labor with terrible anxiety

Hey ladies. I’m 37 weeks and as time is getting closer I’m starting to freak out a little bit about labor. Last Saturday my boyfriend and I went to a child birth class and seeing everything made it feel so much more real my anxiety went through the roof and I was sweating and felt light headed. I have terrible anxiety to the point I start panicking and feel as if I’m gonna pass out and all these terrible thoughts come running through my head. I’m nervous when I’m in the labor room this is going to happen. I have a high pain tolerance so I think I’ll be somewhat okay with the pain but then again I’ve never felt contractions and such before and I feel like my anxiety is going to get the best of me and I’m going to crack in and take the pain medicine. Any second time moms deal with this before? It literally has me so worried I won’t be able to control it and then my labor turns bad because I can’t keep calm.
