well the point wasn't to shame you into self hatred, but i loved the use of his word infantile, because people rarely admit in this place that the constant shelter people take in various substances is often a way of avoiding dealing with problems and how they run away from challenges. "oh! life hurts! let me make a drink..." etc..

regarding your creative juices comment, you might want to try meditation-- it can give you the same sense of depersonalization that your drugs half-assed give you without the negative effects. because the creativity is in you, not the drugs. my suggestion would be to learn from a good teacher to avoid going nutty.
