Often times my issues stem from anxiety and over thinking, doing what I previously commented helped me move on/realise how small of an issue it really was. Different shit works for different people I guess
I yell into things, like I'll hold up a Pringles can and fucking unload all the frustration, anger, regret, sadness, etc for a solid 1-5 seconds. Once I feel as though ive released what I needed to, I apologise to the can, and move on as if nothing occurred.
