i was told early on my parents aren't my friends and that they're to love and protect me. how did you not see that when your parents yell at you, or send you to rehab they're doing it out of love??
first of all i'd stop drinking and doing drugs, your life is already pretty bad and getting drunk/high all day long won't fucking help.
if the situation is this serious id stop gaming right now and actually get a steady job, and move up to bigger things later.
your life is priceless and if its wasted theres no going back.
