It sounds like your mom means well. I'd just let her do her thing or maybe try talking to her about how you feel. I think it's important to let your pdoc know what's going on with you. That way she can treat you more effectively.

I completely understand your lifelong dream about having children. I used to have that dream myself, but after so much abuse and the inability to financially take care of myself, I've decided it's best to just give up on that dream of mine. It saddens me, but I'm trying to make decisions that are good for me and anyone else. I just couldn't provide for children, ya know?

Try to hang in there. We're all there for you.
