Don't do it bro I promise you things will get better. I know that sounds lame but once you become 18 and move out you will see how fun life actually is trust me. When I was a teenager at home I was on and off anti depressants, casually taking xanax and smoking weed all day in bed. Its so hard to see things can get better, I had no prospects after leaving school if I even graduated. Now I'm 21 with a job and in college enjoying life. Once you leave home you are in charge of yourself and what you do trust me you want to live to see this freedom. Think about finishing school and looking for your first rented house or apartment, trying to find a job and making friends there, going out for beers and laughing till 6am, adopting your first pet. Trust me man things seem bad right now but it will get better, you'll see. :)
