They just don’t understand.

I felt the same way at your age and sometimes I still feel crazy. I am 27 now. At your age I started playing the guitar. Playing music helps because the crazier you are the better 🙂 You feelings are completely normal in every sense of the word. You are human and to be human is to be crazy. Your body is going through an immense change right now. New neural pathways are being created, you are growing, your sex drive is developing, you are on a rollercoaster that will not stop. Enjoy it. Step outside of yourself and look at your self. You are an amazing animal. 14 billion years in the making. You get the chance to experience life once. Don’t throw it away. I know what I have said is maybe not what you want to hear, but I see myself in what you wrote. If I had a time machine and could talk to my self thirteen year old self, I would warn myself to stay away from drugs and alcohol. I would tell myself that I am normal and not alone. Many of your classmates feel the same way you do. If you need someone to talk to I am here. Get outside and get some sun. School is almost out. Play outside and enjoy your youth. Take a deep breath and remember you are human; 14 billion years in the making.
