First off, welcome to Bluelight, this is a wonderful group of people that you can talk to without being judged... It's also awesome that you're here and you're talking honestly.
Okay, I'm going to drop some hard truths on you though. This is not about weed. You are an addict, but it seems you already made that discovery. The fact that you recognize this early might save your life. But unless you tell someone, you are going to be on the streets sooner than you think. It may be super hard, something you just can't imagine doing, but you need to tell someone. Not necessarily your parents, but maybe a friend that doesn't use, but that person needs to tell your parents. You need to get help asap. Even if it's the hardest thing in the world, and you think your parents will kill you you GOTTA tell someone because they wont. They may cry and be enraged and all that tough stuff that might make that hard, but you do understand that you have a serious, serious problem. You also need to stop EVERYTHING asap. Which I know is almost impossible, you gotta try. You probably still cannot fathom how much worse this problem can get. 2 more hard truths, considering how fast this happened, you might have a mental illness. I know I'm no doctor, but you gotta check that cause a lot of us on BL (myself included) have some sort of mental issues. The other thing, you probably need to do some sort of inpatient rehab, even at your age. It might save your life. You seriously have no idea what you're getting into...
And this is coming from a guy who just relapsed today and a couple days ago after being pretty clean for about half a year. In another post, people are begging me to toss the oxy I just found, but I just can't. A couple days ago, I took so many benzos (valium, xanax, etc) and drank, I was very close to death... and what for? I just blacked out. I've od'd, nearly died, been homeless, been robbed at gun point in my house... the list goes on. When I od'd I was so close to death that I did irreparable damage to myself. Because of drugs and alcohol, I've broken several limbs. I've had seizures from benzo withdrawal... Dude, don't be like me, please... I beg you.
If you get help and actually beat this before it gets unbeatable, you will make my year. If I can help save you from this life, it would make me cry out of happiness. Seriously, I'm not exaggerating, I would feel like I actually have a reason to live if you get help NOW.

Please make my life worth it and get help
You say that if you could get high, run away, and accomplish nothing, you'd do it... You have no idea what awaits you. As bad as you think it might get, it WILL be worse than you can imagine.
