Sounds to me like you're a teenager. We all go through phases in which these episodes occur. Try and relax more. There are five rules I live by, maybe you could apply them to your life:
1. Free your heart from hatred.
2. Free your mind from worries.
3. Live simply.
4. Give more.
5. Expect less.
I recite them in my mind each time I wake up in the morning. It helps me a lot.
I'll remember you in my prayers. Good luck!!!!
