Pretend the worlds your playgroung and your a kid again.
Me I walk in the park, some times with my mates dog, light Martial Arts training, read a book I'm interested in, play some music, have a cuppa and chat with mates.
Things to try and avoid are getting over excited, drugs and alchohol, enforcing something you don't really want to do on yourslef (take a break get back to it later), consoling your lonliness with sex (generally makes your emotional life even more difficult)
Anyhoo good luck hope you feel better soon.
