Help with anxiety problem?

I have this problem… It’s really bad.
I can’t control my thoughts. I just can’t. I’ve tried but I just can’t. So as a result I have this problem of over-thinking. And because of this over-thinking, I have a habit of creating false realities in my mind that cause me to have frequent panic attacks over small and false things.
An example would be me hearing of the whole 2012 thing in 6th grade. I wasn’t bothered. But in 7th grade, when I had more time to think, my fear grew as I began to think of everything over and over, replaying every detail of my [fake] gruesome death and the deaths of all of the people and animals that I loved. And as I over-thought this, I grew physically ill. My depression grew worse (I’ve had depression since early 6th grade/late 5th grade) and I grew sicker. How I escaped it I can’t recall but my point is that it was bad. And every time a tiny fear sparks, I sometimes sink into it to the point of having to see a therapist multiple times within a short period of time.
First of all, is there a name for this? Is this an actual disease? Second of all, is there a way to cure it? I get the most "relaxation" out of distracting myself from deep thought. But that always ends or I always interrupt it somehow.
I just want help with this problem because I wake up with knots in my stomach. I feel like this anxiety is my body subconsciounsly trying to cause self-harm (because I’ve had a history of it and sometimes think of it to escape pain, but I never act on it). But another idea I have is that I do this to subconsciounsly cover up things that stress me out and scare me so I take it out on the things that give me the most joy or carry the most meaning.
Can someone please help me? I want to know if this is a real mental problem, if it is cureable, and if there is a way of preventing it in the first place.
Blessed be,
Avalessa.
Chaaz, that helps a lot. But I’m under the age of 18. I’m afraid to try medication because I don’t want to have to deal with anymore suicidal thoughts than I already deal with. But I’m glad to know I’m not alone. I was afraid I was going insane.
The fears aren’t just of death or 2012. The fears are of a wide variety of things such as losing my boyfriend, going insane, demons, ghosts, etc.
AndI do have a really bad twitch. Whenever I hold something in one hand, I have to wiggle my hand. Whenever I hold something with both hands, I have to shake it, throw it in the air, spin it, etc. Whenever I hear a rhythem in something like a song or a clock or tapping, I have to twitch along to it until my mind says "enough!". Sometimes I have a mental stutter because of it. I was tested for tourettes so maybe OCD is a right diagnosis?

I thought I was the only one who has serious panic attacks over 2012. Every day I think about it and it terrifies me. I constantly think about how sad it is that everyone I know and love, and all of my pets could all die that day. I don’t want to see my son die. Sometimes I feel like nothing in life is really important anymore because if the world ends in just 2 years everything I do now is pointless. I can’t imagine how scared I will be the year/week/day the world is supposed to end. Everyone will be talking about it. There will be probably be endless news reports, books, newspaper articles, posters, billboards, and websites about it. It will be impossible to escape all the chaos over it. I hope I find a way to control my anxiety problems before then otherwise I might just crack under that fear!

I wish I knew of a way to help you (and me for that matter, lol) but I haven’t figured anything out yet. You should probably talk to a therapist about it. Maybe that could help. And there are antidepressants and things that are safe for minors. Good luck with everything. I truly help you find the help you need. =D Feel free to e-mail me if you need someone to talk to about things.
