I try to read some comics, graphic novels or do some blogging (or journaling). also, going for walks, and getting some fresh air may help. even meditation helps me. I have apps on my phone for white noise, calm and ambient sounds that centers me and brings me back.

also, try doing some simple tasks like making your bed, cleaning or calling a friend or family member. watch a funny movie, video or read a funny book. hope this helps. all the best!
