Does anyone know how to deal with anger issues, cause when I get it I harm myself and I just punched the bathroom sink because I’m angry

Yes. Setting internal boundaries that people can’t disrupt who you know you are. Most likely it is someone triggering ocd which is scary and anger inducing so you need to feel protected from the trigger. Set a boundary such as I am not who my ocd or this person is saying I am. I will feel angry and upset but I will talk to my heart with comforting words that ocd is playing tricks. Also do physical things to make you feel safe. Weighted blanket, music, rain sounds, ice cubes, something soft, I understand anger issues because I used to break things and smash them and throw furniture but I read this book boundaries for your soul and it really helped, so I told u what I learned I hope it helps you too :)

I run or meditate

I have anger issues too. What I realised is that when you try to fight it it gets worth. I learnt to use it for the ‚good‘. When you stop fighting against it and using it as something that drives you it can have a positive impact. For example I use it in sport I just let it out there. I use it in art. I express anger through writing something. And when it is an extremely bad episode where it’s extremely hard to control I either leave the house and just run till the anger is gone or I lock myself in a room and scream without letting my voice out till I feel better. My motto is however I let it out I will not harm anyone, anything or myself.

Or punch a pillow if I need to punch something lol
