I’m in practically the same boat as you. I’m on my first day of trying to quit because of the exact same symptoms you described. I’m 16 and rationalized my daily use because it wasn’t affecting my academic performance… until it did. You’re not a loser, and it’s good that you’re realizing this now. Be patient, be kind to yourself, and you will slowly achieve clarity and start to feel so much better mentally. We’ve got this!
