I don't think too many of these guys have had experience with drug addiction. Smoking weed in place of MDMA is not going to help you. Doing other drugs in place of MDMA is not going to help you.

Get into recovery! Everyone who has given you advice on HS forum is an admitted drug user. NO one is in recovery here.
You need some god damn tough love... not congratulations and fucking internet high fives. you need real help. Again, it would be wise and responsible of RIU to provide you with a adequate link to find help/recovery. start here:
