I used to have a huge fear of public speaking, then took a couple of speech classes and cured myself of that. I teach classes in my spare time and don't have an issue with that.
I don't have a fear of speaking, I just don't have a lot to say. I think it's more of a confidence thing with me. I don't think people really give a rat's behind about me and what I think. If I'm around people I'm comfortable with, I'm a lot more talkative. But remember, my relationship went downhill and I wouldn't count my H among the people I was comfortable with. So I kind of got into the I know he doesn't give a rat's behind about what I think, so why bother?
And before you start swinging at me, I am NOT defending my logic, I am just portraying who I was in our marriage when it was starting to fail. It was NOT good nor healthy the things I did.
