I had a very similar upbringing/issue with my life. The only difference for me was that my mother had me doped up on 8-10 different psychiatric medications that I didn't need all to try to control me and she would use the mental health system to have me locked up as a way of "punishing" me for defying her. I had a lot of explosive anger issues too where I would get angry and throw fits or lash out at people or even punch and bite myself out of pure anger because my mother wouldn't let me be a normal kid at all. I wasn't allowed to make friends or be normal in any shape of the word. The only happiness that I had as a child was my computer and books. If mother tried to take either of those things away, well let's just say I would get so angry that the cops had to be called in to restrain and handcuff me because I would get physically violent because I had nothing else to do and nothing else made me happy since my mother wouldn't let me leave the house to make friends or play outside at all.

With that being said, I mellowed out a lot since getting away from my mother and moving out on my own. Now, my anger issues don't interfere with my life too much; as long as people don't try to control me in a major way or become a threat to my well being, I am calm around people.

My best advice that I can give you, which has my own life as evidence to back up my claim's credibility, is to get away from your mother ASAP. She won't ever change and people like her have absolutely zero business having children. If you're under 18, seek therapy and try to gradually work your way out of her grasp. As long as you're over 13, you can legally attend a therapy session on your own without needing your mother's consent.

Do whatever it takes to get away from her. Once you do, I promise that the anger issues will gradually dissipate.

Best of wishes.
