Anybody else do this?

Mine are basically:
<ul type="square"> [*] cutting[*] not eating properly [*]ODing occasionally [*]drinking alcohol knowing it will make me feel more depressed and more self-destructive[*]going out for "walks" at night knowing it might be dangerous [*]Sabotaging my own education[/list]
I don't always do these things. Wondering what other ppl's forms of self-destruction are...
