Posting sad poetry and songs is very characteristic 4 behavior. It's hard for 4's to pull themselves out of a hole (not that csw doesn't have plenty to feel bad about). Fours don't usually distract themselves from feeling bad (unlike a 7, for example, who usually has no trouble distracting him/herself). As a 4, I find that I feel dishonest when I try to distract myself from something that is really bothering me. When the sadness is the most authentic thing going on, I can't unstick myself from it. Oh, how I wish I could!!
