I am not a doctor, but I can tell you that I have a grandson who is sociopathic. I urge you to find a good psychiatrist or therapist as soon as possible. Be open and honest with the dr. so you can get the help you need as well as a good diagnosis.
Keep in mind that sometimes a person has to visit several psychs before finding one that they are comfortable with. Your rage against people is something that you must get help for....even if you have to go to an emergency room
Best of luck to you..
