Something weird happens to me is it a medical issue?

[Toli]

Ok first, I give very negative vibes to people like i want to fight them. Almost everyone I come close to, If i even fear that im going to give off these negative vibes it starts happening. Another thing that starts to get to me is i get angry because it keeps happening so i do it intentionally and stare somobody down. This person could be any size,could be nerdy, gangbanger, arab. and after i do that i feel a hint of fear and look in their eyes and see them smile as if they felt my fear. I questioned it at first, but it has happened to me countless times. One day it got so out of hand, I was so angry that it kept happening and i could do nothing to stop it i started to breath a little bit quicker. I was at a computer at my school with a pretty muscular dude sitting next to me, I felt the fear, seen his gratification of being feared and his little smirk. I started breathing faster and faster untill my fear turned into rage. Adrenaline was pumping through my body and i started to feel numb. I looked back.. I felt no fear. and turned to my computer. As this happened i was on the brink of should i smash this kids face into a keyboard or let it all go. I let it go and let the adrenaline subside. Is this a medical issue?? After this i felt very good like i let something out of me and felt very tired and sleepy
