Whats wrong?

Ok. I have been having some doubts about my mental stability for a little while now. So I will describe my symptoms and maybe someone can help me out. I get paranoid. Like having to get up at ungodly hours to make sure the house doors are locked and my dog is in the house. I feel uncomfortable around people. But not in a shy way. In a way where I dont want to be around them. If feel even more uncomfortable without music and feel threatend by silence although not severly. I often lose my grip on reality like thinking that people can read my thoughts and having conversations with friends that are not there but I am semiconcious that Im on my own... I know but I ignore...I often have involuntary thoughts like random things popping into my head. Nasty things. Like hurting people. I also often lose my track of thought half way through speach and move onto another subject completely or repeat things i have said already. I also have random outbursts of anger and often yell at people nedlessly
