Anger is a fairly common human emotion: one that hails from an defensive position or one that stems in rejection.
I have personally been expierencing moments where anger seems to come out of nowhere; today was unbearable. At some points I was so angry I was unable to speak, I became physically ill. Sat down and closed my eyes to breath, I envisioned myself in the mountains close to where I live, but holding a sword. A lake appeared before me carrying a televison with its tide. I destroyed it. I went on a rampage of destruction and at the end, I was crying because I realized I hated everything; I don't care about anyone or anything, literally not one person on this planet. I was done, I was weak and I hated this place. I don't want to die, it was not a feeling of wishing for suicide. There is no depression, no sadness, just anger. Anger at being stuck here, anger because it never ends. At that point I could have cared less about ANY human being. I just wanted out. I wanted to be nothing and stop existing.
As I went into work, I bawled my eyes out in the staff bathroom and had to tell myself to hold it together as I stared into the bathroom mirror. And I realized there was no mirror and I was angry, and I wanted out, felt powerless. I had to breath and remind myself I need my job before going to my till.
What the hell is going on here!? I have no idea what the hell is happening anymore!!!?
