If im feeling really stressed out or really down (which i very frequently do), i either drink excessive amounts of alcohol and passes out, cause it gives me a few hours when i dont think about the problem at hand plus it gives me something else to think about the next day, most often what i did the night before, that's always a tricky one to remember, or if i dont have any alcohol i eat alot and smoke alot.
None of them are healthy in any way, but they work for me, atleast short-term.
