Firstly, a nice long hot shower could be what you need if you’re up to it.

I think anything involving getting in touch with your senses could be good. I’m struggling with a bout of anhedonia right now. Something I’ve done for the past year and a half is write something good that happened each day on a sticky note.

Attempting to enjoy whatever sun there is.

Being outside and spending time in nature.

Putting on a movie / TV show, especially feel-good ones

Watching comedy on YouTube

Remind yourself that your thoughts are just thoughts.

Don’t worry about the clothes :)
