Fear of giving birth

I had my daughter at the birthing centre and I was really proud that I was able to do it without medication but this time around when I went back to the same birthing centre I could feel my teeth chattering and my palms sweaty and I feel myself not breathing. With every step my heart would sink. I’m now reaching 40 weeks and Everytime I get contractions (false labour ) this sudden fear just completely overwhelms me. It’s like everyone’s looking forward to birth except me I’m just so happy it still hasn’t happened yet 🙈. I really don’t know how to overcome this and be stronger because the more fearful I am about this birth the worse the pain will be and I not only physically but mentally will not cope. Pls advice.
