One step at a time my friend. just keep working through the days, encourage yourself more and more. as each day passes the struggle gets lessened.
don't feel ashamed at all for NA meetings. they are absolutely wonderful. i'm 19 years old and went to NA, i gained support from everyone around me, i was nervous and shy, and there was hardly anyone there my age. it kept me sober for 6 months straight until i stopped going and fell into my old traps. it truly is a magnificent place to recover and establish that you are not alone in any situation you think you may be in.
a 6 month addiction is still an addiction - and i think you have to realize that in order to gain an understanding of what could happen if you continue down the path of drugs. it doesn't matter if its a week or a month, for however many days you were hooked on a substance, it will haunt you UNLESS you overcome it. and you can do it!
if you really can't resist those pills then throw them away. that was the first thing i learnt in NA, get rid of everything, stashes etc. when you have nothing in the house it may drive you a little crazy for a day or a week, but once you establish that you DONT need those drugs. at NA i was also given a "bible" so to speak, of stories of addicts around the world which i would pick up whenever i thought about drugs during my sobriety. it helped so much you can't imagine.
give it a try - and if you really don't like it, you don't have to go back
have you been to see a therapist/psychotherapist about your problems regarding drug use?
if you ever need to talk to someone about anything on your mind feel free to PM me. i'll get back to you as soon as i can and whatever you say to me is purely confidential and won't be shared with anyone and i'll try my best to support you with whatever i can do best.
keep on going, you can do this!
