Your post really hit me...know it has been two years since your wrote, sure hope all worked out well for you. Starting in 6th grade...but the rest of your story sounds like you are pretty responsible...so I wonder why you would have taken anything in 6th grade. If you have not fixed situation...you do need someone as help...parents are best if there are not issues that may have caused use in the first place...otherwise, counselor at school...they do not necessarily tell your parents all...but that person could set you up with actual person who's specialty is your situation. You sound like a great person...who just made a poor choice, but a seriously bad one that anyone would get hooked on no matter whether you are normally a responsible person. Hope all is well now.
Just a quick note to say hi!
