Okay, before you tell me to see someone, I am. I have regular appointments with a doctor, psychiatrist, and therapist.

The fact that I do not know what't wrong with me makes my anxiety skyrocket.
Okay... I went to my doctor(my mom's doctor first now mine as well.) because I has this weird trembling feeling that I got when trying to sleep and my heart would beat really fast. She prescribed Paxil saying I had a Serotonin imbalance. It got rid of the trembling but nothing else. I had always been paranoid and shy, and somewhat rejected by the world. I developed trust issues very early in life and was terrified of germs and stuff. After awhile(when I was 16) things became strange. I began snapping and having reactions to things that didn't match my emotions. I was paranoid and believed that I was pregnant with the devil's child. I eventually got the Paxil prescribed that year and started seeing a therapist. I remained somewhat paranoid through all of this. But in the past seven or eight months, things have gotten even worse.
I am incredibly suicidal and hear things sometimes. I have cut myself(with my finger nails and once with scissors), I even kicked my dog once because I got nervous/angry at a teacher on the phone. I can no longer look people in the eye when speaking to them. I can't talk on phones, I broke up with my boyfriend even though I still loved him but I suspected he may not care for me, which is completely untrue. I have felt things that aren't there( IE water dripping on me, and something reaching in my pocket.) I cry very easily, I can hardly concentrate on anything, sometimes I see alot of colors blue, I carved random scattered thoughts into my dresser, my thoughts "attack" me and feel as though they are being pushed into my mind, I feel like no one ever forgives me for anything and constantly think people are making fun of me.
I left my last therapist because I thought she was making fun of me, but since I feel I can no longer trust myself, I am not sure.
What is going on??? No one tells me anything! If I don't find out, I will become more afraid of myself...
