I have similar problems with my mom. She had a head injury when she was 17 and it's really difficult to deal with her irrational thoughts, and her ability to not keep a secret.

I had to make sure that all my doctor's offices only have my cellphone number for contacting me, because everytime the phone rings for me, my mom listens in on my conversations. It drives me batty.

She ended up telling the entire family about my MS before I was ready to out myself on it.

She's a serious drama queen too. If I complain about a weird MS symptom, she has to one-up me with a worse problem.

I just keep my mouth shut, we got cordless phones in the house that tell me if someone is listening in, so I can tell her to get off the phone, and I dont tell her anything that I dont think she needs to know.
