How to deal with internalize anger/suppressed rage just being more aware
So I am talking to a friend and she say lot of my behavior is very rude and insensitive which i now see. I have cptsd/autism and I am starting to realize much a shitty person i have been without realizing it. She also said i sound like I want to hurt someone when I would socialize with her and I know see most of my life I been projecting this to others scaring the shit out of people or making them uncomfortable.
I feel so bad on how much drama/pain I have caused how much I was in denial. Even with medication I still am very angry socially wise but not as much emotional currently.
I had punch my door and wall 3 times in total, I have been to therapy but I never really address these anger but some therapist I have tried fixing it but I never actually changed.
I know can change not be like this in the future. I just can't believe i been like this for so long and how blind I was about my behavior towards others.
I want go back to therapy but I don't have the money for it right now. What can I do?
