I am pretty sure I have misophonia?

Ok, so I don't know what to do. All eating and breathing sounds piss me off to no extent, I often have thoughts of either killing whoever is making the noise or killing myself so I won't have to hear it anymore. I will flip out hardcore on someone if they chew with their mouth open, I used to get in trouble and yelled at constantly when I was younger because my dad chewed with his mouth open and i yelled at him everytime to stop. I can not stand hearing people chew with their mouth closed either, I can hear all the saliva sloshing around in there, I can hear their teeth banging together, I can hear them swallow, and if they are eating something crunchy I lose my ****. I can't even stand the sound of me chewing, it irritates the hell out of me. When I can hear someone breath it makes me want to punch them in the neck,I just want to rip their throat out and kick them in the head repeatedly until they are dead. Anyone who snores I want to just put a pillow over their head until it stops. I currently have a roommate and we unfortunately share a bed because we live in a 2 room apartment (if you count the bathroom as a room). I always wake up early in the morning because he chews nothing in his sleep, just smacks his mouth in his sleep, and I just want to strangle the life out of him, so I will yell obscenities loudly to wake him up so he will stop it. Ive gotten in trouble at work cuz ill hear someone eating or breathing and i freak out on them. Idk what to do, it ruins my life
