I don't know what a therapist would say, but I find your coping mechanism quite interesting! I take everything I hear to heart, I take it personally, I take it hard. And I tend to mull it over for far too long, and the longer I do that, the bigger the monster becomes. I think if I could do what you do - assign those voices to characters, maybe they would have less of an impact on me. People's opinions can only hurt us when we allow it to. If we can take a bully's voiced opinions and envision those words coming out of the mouth of a cartoon Bullwinkle, maybe we could laugh them off instead of internalizing them.
