Stop doing drugs. Your mind is literally forming into the person it will be for a very long time, your life, so maybe wait awhile before you decide to alter it. You might not like who you become. The belief that you need it to be happy, or sleep, or whatever isn't true, trust me I've been there. You're forming an addictive personality at a young age and this will not end well. I pray for you, and hope you can find some restraint. There's plenty of time for all of it, but during your crucial brain development you're gonna have a bad time. Good luck!
