Listen for that internal pull to watch TV or youtube. When you hear it, note it and go for a walk instead. Exercise – regardless of your situation – will always be the better choice. It will make you feel better emotionally and physically.
It also sounds like you’re onto something with the art class. Get out there and do the stuff you’re interested in. Note: If your interests are TV and youtube, shelve those for now. Find stuff you really enjoy. Do you like walking in nature? Birding?
I would also recommend volunteering. Is there a soup kitchen or shelter in your town that you can get to? They often need help. What about a trails committee? Volunteering will give you purpose, get you out of the house, and you’ll probably meet people.
Remember – TV and youtube are to be avoided. In fact, it sometimes helps to listen for those strongest desires just to find out what to avoid. Shake things up.
