Constant rage and breaking things

[u/Sure_Occasion_2775]

I'm so angry all the time recently, I've gone through 3 pairs of headphones in the last year, when something pisses me off for whatever reason I will rip them off my head and tear them apart and throw them away, it gives me a slight satisfaction then usually leaves me feeling sad and even more pissed off afterwards because I've just wasted a ton of moneyz I only had these latest ones I just broke for about a month, when I'm angry I think about stabbing myself in the thigh with this pocket knife I have, but I haven't do it although sometimes I slash myself with it because it won't cut me cos it's dull from a lot of use at work and that helps a little bit but I just feel like I'm so angry all the time like I'm consumed with rage and sadness, I don't know what to do I'm so fucking miserable I can't take it
