i take a long hot shower and shave my legs even if it's winter - something about focusing on removal really helps me to take my mind off of whatever is bothering me. i'll wear my favourite comfy pants and order in whatever food i want (i don't have the energy to cook when i'm down). then i'll usually watch some sort of cartoon to distract me.
oh!!! and one of my favourite things to have when i'm down is the milk drink from ponyo - it's a little bit of honey, cinnamon, milk, and hot water and it's REALLY GOOD. sweet and hot and delicious
music. Music all the way. Whether is going out in the car or just for a walk in the park... or maybe going with my friends listening to music and smoking some weed.
I like to draw, listen to music, and look at videos on Youtube when I'm having a bad day. If I'm having a really bad day, I rant about it online hoping people will feel sympathy for me and my actions were justified.
