These Mood Swings are so fast they’re going to break my neck

I keep going into fits of rage. Not even lust. I’m so angry. At literally any and everything. I can’t tell if my body’s reregulating from the lack of dopamine or if my base head space has always been like this and it’s been on mute. I get periods of excitement and elation but I crash super hard and I’m furious. My body feels so pent up like it’s going to explode from my guts. I dont even recognize the voice in my head as my own anymore when it starts whispering the negatives. It genuinely feels like I have some kind of mental parasite. Anyone else dealing with this?
