Freaking OUT

I'm a FTM and I'm 34+2. I'm starting to get major anxiety about the birth of my son. I've wanted nothing more than to be a mother since and long as I can remember. I'm 31 and my husband is 36. I know we are ready for this...I'm just starting to get so scared. It's getting so real. I feel like I'm going to be scared for the rest of my life. I don't know if I could live if anything happens to him and everyday of the rest of my life I'm now going to worry about that. I'm nervous for delivery...will everything go ok. Will he be ok? Will I be ok? My mind is racing....
