Do you have any interests or hobbies that you can do? And not only right now (although if you're bored, it's a good idea) but as a way to socialize?

I like soccer and writing and motorcycles. And through Meetup and searching online I found groups/clubs for those interests, so I'm able to 1) do stuff I'm interested in and 2) meet new people doing it. Plus, if you're in a social setting with a purpose it's easier to talk to people. "Who's your favorite soccer team?" "What book are you reading right now?"

I found it really helpful and met some good friends that way. And even if you can't go join a book club today, just researching different possibilities is a way to kill some time.

Another idea is a support group for mood disorders. It might help with the hopelessness and also give you an opportunity to meet people.
