Welcome Context, I think many of us found SR on a drunken Google search, and have found sobriety because of this place. You are very wise for such a young age, I know I will not be the on,y one who says "I wish I had quit at your age." I definitely do!
You can do this, one day at a time, and in the beginning it may be one hour, or one minute, but you can do this. SR is a great support, and you may benefit from other outside supports as well.
Looking forward to seeing you on here!
