Generally, I just act like Mr. Spock: I analyze feelings rationally, as if I'm standing far away, observing the biological and neurological reactions of the human body to outside stimuli.
I do notice you didn't include various self-injurious behaviors, such as drug/alcohol use (well, alcohol is only injurious if you're using it to cover up your feelings, but you know what I mean) as coping mechanisms. They are, of course, dysfunctional coping mechanisms, but they do exist.
My own "coping mechanism" of last resort--ashamed as I am of it is something like this. generally involves deliberately injuring myself... not badly, of course; just scratches, enough to hurt a little. I don't know why it works; it must be the endorphins that your body releases when you are hurt. Still, such self-injury is getting quite common, especially among people in my own age bracket (22 years old) and younger. Personally, I discovered the calming effects of self-injury at around the age of five or six; but from what I have seen, it seems to be more common during the teenage years.
Do be nice to me, though, and don't use the words "sick", "angsty", or "attention whore", or "weirdo" in your reply if you comment.... thanks.
