Im sorry to hear your feeling this way.
I would suggest looking into calmbirthing or hypnobirthing and doing one of their courses. it really helps a lot of women.
Hiring a doula is something else you can look at. they are awesome.

pregnancy is magic time and birthing the baby is special. I hope soon you can feel calmer and enjoy the next few months :hugs:
don't forget your body is designed for this
