why is exercise not an option? i find it to be one of the main instant pick-me-ups for when i'm anxious/stressed/upset.
other things, though, that help me include cooking something at home; spending time with children (siblings, nieces/nephews etc), visiting friends, alcohol (although obviously in moderation and depending on how bad you feel, it could end up making things worse) and one of my favourites is shopping for clothes xD - obviously only if you have the money to spend, though
