i find going for a walk helps me, reading books, watching anything funny. also the other thing is journalling. i always feel better on the days i journal. i aim to write at least 2 pages or for at least 20 minutes. it helps me get perspective on things
hot baths are good. sitting in the sun
i also use rational emotive therapy to analyse if something specific is upsetting me and change the way i am looking at things
talking to friends is good

dancing is fantastic
deep breathing works for me. i have never mastered meditation but i just do deep breaths in and out for a few minutes sitting with closed eyes and that helps
watching my dogs play! my pets give me so much joy. cuddling the cat or the dogs
