I can relate alot your story, I am also 21 and was addicted to hallucinagenics such as LSD and shrooms + a whole other catogorie of drugs... however I went to rehab for 2 years to over come my addiction and now I have been clean for almost 3 months (not including time in rehab). So Ill be the first to tell you this thing is hard, but it is possible, there is light at the end of the dark tunnel that you are in! I followed the NA 12 steps and the celebrate recovery 12 step programs in center and they are effective if you work them daily... so dont give up and keep going.just some advice dating is not such a good idea at this stage especially not with some one that has just come out of addiction. I have seen many people try it some of them are now back in full fleged addiction and some are dead, so be very carefull. I vowed to myself that I would not date or get involved in any sort of intimate relationship for a year, so that I can get my life in order, so that when the time comes I can actually contribute to a relationship... hope this helps. and stay strong
