Hello!! How old are you?? If you are 18 or close to 18 you couod try a medicin called Paxil. I have since my teens struggled with enourmus anger and tantrums the way you describe you are doing and after I started taking Paxil I am no longer angry. I feel like myself and it is a tremendouse relief. I advise you to consult with you physician and give it a try.
Wish you the best of luck!!
