I couldn't do the cake thing..but that does sound really good
When I have a shitty day, I generally need to sleep it off because sometimes there is no other way to change my mood. Sometimes occupying myself with other activities or talking with someone else helps, but not always.
When I feel crappy I wear my most comfy pants ever (sweatpants for the win!) make a hot tea/ coffee and sit and watch a movie. Movies normally make me forget whatever it is I'm feeling crappy about...
Max, today I went back to school, which definitely qualifies as crappy. If I don't post on here for a few days, it's because I tried one of your remedies in the middle of the campus library. I won't say which one, but lets just say I'll be in jail for indecent exposure.
