hm…. this is a great question friend!
when im sad, the first thing i’ll do is usually talk to someone who i really trust about it, and sometimes just that can make me feel better and sort out my feelings.
if that doesnt work, i like to take a nap because something about sleeping really brings clarity and peace of mind
also i have a playlist of really happy, soothing songs that i associate w/ good memories, and ill listen to that. i also like watching choreo videos.
sometimes ill take a walk in the park bc my uni is like this massive circle with all the buildings on the outer ring and inside is this massive park, so it’s nice to walk around and get some fresh air.
often times, i need to unplug for a little while— like, not go on tumblr/facebook/and form of social media bc it can really contribute to depressive feelings and just getting away from that for a certain time period can be cleansing.
i also go to my temple a lot. im a theravada buddhist and going to pray and talk to a monk really soothes me, and i leave feeling really at peace.
these are most of the things i do to cheer myself up!!!! hopefully something helps you as well :D
