Unexpected Freak Out - Don't Want To

I'm really hoping it's hormones or something but I'm almost to the finish line and despite going for my doula certification and being a total birth junkie literally my whole life and incredibly natural minded and excited for birth (already done it before!), I'm suddenly just really distraught and i don't want to go to the hospital and i honestly don't want to do it. I know it's childish and weird but i just don't. I feel like im being forced to do something. I feel like vomiting and crying (and actually do sometimes) just thinking about it. I don't want to give birth. It's not that i want a c section or an epidural, i just don't want any of this to be happening to me anymore. I want it all to go away.

Please tell me you've had similar feelings and it passed. I'm so scared and angry. :(
