Treating a drug addiction with more drugs is not the answer. I myself once dabbled in the white stuff a little too much, say 7 years too much, before curbing it albeit i didn't find myself wanting to die if i didn't have it. You just need to surround yourself with less drug orientated individuals and live your life as normal as you can. Soon you'll think less of getting fucked up, and more of improving yourself and relationships with others.
