I can really relate to how you’re feeling with getting angry at these things, I have really struggled with my anger recently. For example if I smiled at someone at work and they didn’t smile back, i would just feel like the worst thing had happened to me and that this person had disrespected me so much and that maybe I don’t even deserve to be smiled at and so on. All these thoughts would rush through my mind for hours and it was hard to stop them and I’d get so hot and tense and I’d just want to explode. And literally everything would just make me angry and it could take days to calm my self back down and nothing would cheer me up. I stopped talking to my friends and family, I stopped working, I basically isolated myself from everything because I felt like everything annoyed me.
Then I had counselling from the NHS for a few weeks which really helped so maybe go and see your GP and ask where and how you can get some support with it.
But also, exercise. Punch a punching bag, run around or maybe just walk. And try and do it everyday and slowly things will stop making you feel so angry.
And make time for your self. Turn your phone off for a few hours and do what ever you want, even if that’s watching funny YouTube videos (worked for me) or anything you like.
You need to release your anger and find nice things to replace it with, and these things will give you something to focus on when you get stressed and it will help
Isolating your self will make you feel worse..I’ve done it and it honestly didn’t help. Once I started talking to my friends and using up all my energy at the gym I started feeling better and now when something does p me off it doesn’t effect me for a whole day, just a while instead. It’s taken a lot of work and I still have good and bad days but it’s nice to not be so angry and and miserable all the time and to be able to breathe and just feel enjoyment.
I hope that helps and I hope you feel better soon
I wish you all the best!
