I Believe That I Suffer From Paranoia

Hello, I am a new member. I am currently taking counseling sessions because many people, including myself, are worried that I am suffering from depression and or paranoia. After a few sessions with counseling my counseler is certain that I am not suffering from depression but is starting to grow more worried about my possibiity of suffering paranoia. I am only 16 so I don't think she can legally diagnose me with paranioa. I think I have paranoia because my life is a living hell in my mind. I have moved many times and have been to 4 school districts. The school district I am in is not new to me. I have known these people for 5 years, but even so my mind turns my closest freinds into my closest enemies. If someone said something like "Hello" I would see it as a friendly gesture but my mind would convince me that there is a bit of a mocking tone underneath it. This doesn't happen all the time but it has gotten to the point where I think my own family is mocking me. In my mind almost everyone mocks me, hates me, and even a few want me dead. Now don't get me wrong I am not in anyway suicidal. I frown on suicide but think that it is one's own choice. The only person that doesn't seem to mock me in my mind is a very close friend that I have known for years. He is basically a brother to me and even my own family has accepted him as family. I only see him once in a while though but he usually stays for a week. He too suffered paranoia but only a minor case that seemed to have eventually pass away. I have come into full relization of my paranoia about 2 months ago but it has become bad since then. Everytime I open something new on the internet I have to delete all browsing history including internal memory hardware in fear that somehow (though almost imposible) someone will find anything to use against me. As my paranioa grows so does my anger and violence though I don't take it out on anyone it becomes pretty bad and I feel bad for my walls......My mind doesn't think if anyone will read this but if so please don't think I am lying (another paranioa problem...I feel that people see everything I say is a lie). Sorry for the long story by the way.
