Dear youngster,
I know what you are going through, you are under a lot of stress you don't know how to deal with. When I was younger, I went through it also. I found the answer for me when I came across a tape, "how your mind can keep you well". It is a meditation that saved my life.
I had a bad childhood and was very angry, anger and resentment caused my problem. The meditation can help you overcome it also.
You can find it at Amazon, it is cheap, but worth a million.
I hope you try it. You can also get it at fhu.com, ( the foundation of understanding.).
Calm down and don't let the symptoms scare you, you will be alright.
Louise
