I have a confession. I'm ashamed of myself.
Do you have a reason why you are ashamed of yourself?
I don't like some of my behaviors.
If you have behaviors that you are unhappy with, then you should see a therapist to work on controlling or eliminating these behaviors. The behaviors will continue to get worse and more unacceptable unless you get help to stop them.
Therapy doesn't work. It didn't help.
I'm sorry this didn't work out for you. It is good that you want to change things that you don't like about yourself. There might be other ways to change them yourself if you don't like it.
