What to do if i have these mental symptoms, that i am aware of?

Your age is a tough one for many, don't label yourself paranoia if it is just growing pains. May I suggest you turn to the Lord? He will help you thru the difficult teen years. Get a Bible and read it, and find a Bible teaching church. Then get involved in a Christian youth group. You will never regret asking the Lord to come into your heart, and to make all things new for you. God truly does love you, my friend, and so do I. Give God a chance. Your life will never be the same.
