Living well is the best revenge. The second best revenge is carefully removing plants from someone's garden & replacing their lawn gnomes with slightly larger lawn gnomes so they appear to be growing in size from eating the plants.

Cancelling plans is okay. Putting yourself first is okay. Going for a long walk is okay. Abandoning society is okay. Moving into a cave with a family of raccoons is okay. Giving them tiny swords & shields is okay. Do what you need to do to cope.
