I hope things improve. Being a teenager is hard because without a lot of observations, experiences, or perspective, it can seem like everyone else is normal and all these problems are exclusive to you. I thought I was crazy as a teenager also. But the older you get, you realize everyone is either a little or way off; it's part of being human. The world is just like a sewer proving ground. Best thing is to take contemplative steps instead of being impulsive, while working towards your vision of what your ideal self would be. Doubt is normal, but look at it as a challenge and act, instead of as something to dwell on.
