Any really cozy/comfy vidya or anime to deal with sadness...

Tamako Market is my go-to when feeling sad. The opening alone makes me feel nostalgic, but I guess that's a personal thing. In general, the show is very relaxing, and deals with heavier stuff down the line, but always with a grain of sugar. If you can, also, read some Komi-san, a very heartwarming manga, and be safe user, I also use vidya and anime to cope with depression, and I hope you can get behind it.
