I understand fully what you mean. Sometimes saying what is inside you stays there forever, and other times it just starts coming out one thing at a time. The first time you say to yourself, I don't believe I just said that, and are either proud or embarassed depending on the statement. After a while they just seem to escape from within, and each time some internal pressure is lifted.
I too deal with anger and fear but lately have been telling people that piss me off just what I think, but there are still fears inside, cant get rid of those gremlins.
If you ever want to talk, I am here.
At least you recognize that you have these issues and you are trying, that's all you can really do.
Keep your head up xoxox
