Abusive Relationship

I think I am in an abusive relationship with my mother. I can't believe it's taken me this long to realize it. Now I don't know what to do? Of course I am talking about emotional abuse, not physical. The worst part is, she thinks she is the victim and that I am an evil uncaring person. Sigh.

For example:

Today the Hospital's Occupational Therapist took my husband and I on a tour of the NICU unit and showed us some babies that were born the size our baby is right now. They wanted to give us an idea of what we may be facing. Of course this was sad and emotional and as I was trying to share this information with my mother, instead of listening to me, she is constantly interrupting me to tell me repeatedly that I have no business having children because I am not healthy and that I need to have my tubes tied because I will have a stroke and then my children are going to lose me and she is so serious that I really need to listen to her and have my tubes tied and never get pregnant again. On & on & on, she won't let up on it. So I try to change the subject which causes her to complain about more and more things that are so difficult for her because of my situation.

So I called my husband totally upset that my mom is making me feel even worse about everything that's already horribly sad in my life. Side note, I just remembered: When I first told my mom I was pregnant with my now four-year-old, I was about 5 months along already, and her response was to complain that I shouldn't have any more kids and that I should have told her about the pregnancy sooner so that she could have told me to get an abortion.

A few minutes after telling my husband, I get a call from my mom. "I'm sorry honey, I didn't mean to upset you. I don't know why you had to tell John. I hate how you always do that. He called and yelled at me, I just hate that." Complained about a few more things. Then I told her I had to go.

I think I know WHY I have high blood pressure. I think I know WHY I am unhealthy. But how on Earth do I stop it? HELP!
