Afraid to hurt the baby

Alexandra
I have anxiety disorder, PTSD, depression, sleep disorder, and bipolar I. I am a victim/survivor of child abuse; in every form. 
I'm TTC with my boyfriend and I'm terrified I'm going to screw up the baby somehow. Or that I'm going to be a psycho pregnant woman or someone who gets post partum. Is anyone else struggling with these fears? Has anyone else surpassed these fears? And, how? What do you recommend?
