Man, I can't possibly imagine what it feels like to be you right now. It is probably terrifying.
You really should sit down with a mental health professional though. It may not seem like it is the most important thing for you to do right now. Also you mentioned something earlier about dopamine...I really hope that you are not taking it, because that would be the last drug someone with paranoid delusions needs. High levels of dopamine is the main biological sign of schizophrenia, and normally is only prescribed to people with Parkinson's disease. When is the last time you were at the psychiatrist, you may need to have your medication adjusted. I really do want to help you, but it is so hard to convince someone that they need help in person yet alone over a forum. The best person you could talk to right now would be a clinical psychologist, but that is just a fancy term for someone who pursued a higher education in psychology but did not want to go MD to prescribe medication. They generally disagree with a lot of pill pushing psychiatrists. (Source of opinion = My girlfriend = studying to be a clinical psychologist)
You need real help, and although I would like to think that these posts are helping you. The sooner you get help the better off you are going to be. If this continues down the path it is currently on, you may end up to a point where you are dangerous to yourself or someone else. Unfortunately mental health care isn't very good, even in the US, we are getting better but there is still so long way to go. Good luck with finding a solution to your current predicament.
