Am I alone in feeling this way?

My husband and I are to the point of wanting to start a family. I have bad PTSD with a traumatic case of endometriosis and emergency surgery that came along with it. Almost loosing my life left my scared. Carrying a baby and the trials that come with it absolutely terrify me! But I want so bad to have a child of our own blood. I’ve thought about surrogacy and briefly discussed it with my husband. But I’m just curious if anyone else has gone through this and has any advice to share. Neither one of us is getting any younger 🙁
