Would it be stupid for me go to NA?!

I'm seventeen about to go to college still deciding if I'm going to ucla, csun or an instate school. I feel as if its time I get help before I go to university where parties will be a weekly thing.

Well let me talk about my drug use: I started smoking marijuana around fifteen and then I got into binge drinking. This was with a close family member. Even before that I would Save up tylenol and other otc and take them all at once but I know it wouldn't get you high just something to do. Then I was smoking marijuana a lot and drinking whenever I could but I did have breaks. Then I got into prescription drugs....I stole some pills from my cousin also after his surgery and I was takin vicodin while drinking alcohol I could find. I took a break from that and went back to smoking marijuana and drinking. (Not everday) but then my friends and I got crazy idea to do ecstasy and all this other ****. I ended up doing ecstasy more than once. I also tried some psychedelics. Then I got back into pain pills but this time lortab...there was a point I was withdrawing from them and I couldn't sleep but then I realized I couldn't do this **** so I managed to clean up. So basically I'm clean now since november but I still have urges to do drugs. Seriously if someone asked me to do anything I would. I made connections with people who use heroin but I haven't really contacted them but the thing is I can at any moment which scares me.

Yet, I keep thinking what I've done is nothing serious. I also think that ill be fine and can handle this. My mother only knows I've smoked marijuana but not anything else. She asked me if I ever done e but I denied and she believed me. The thing is I don't do it now cause I'm on anti depessants so I can't even get high on it and its also dangerous to mix the two. Yet I found myself looking through my moms room for her hydrocodone....I don't know what to do. I don't think I'm an addict though.
