OMG, I'm in such a similar position (except for the children) - please be my friend! ;)
Moved back to the childhood city 5 weeks ago. My partner has a job starting in 1 week but I don't. I've been working on starting a business, but it's been slow going. Mostly because we've both been in vacation mode and I don't have a lot of my own space or time or furniture/stuff.
Suggestions:
- take a course - either something totally fun and frivolous or something that may increase your employability. For me these are video game design, and accounting. Or something through the city or community association if you want a class with people around.
- start a business
- look at Meetup.com for random meetups in your city
- try a new activity/sport - my favourites are martial arts and roller derby. I started derby in May and it really helped my adjustment to my previous new city. I start again in the new city next week. Most places have the season start for newbies right around now.
- go to each park and neighbourhood just to walk around
- go the library and get whatever random book/magazine seems interesting
- use kijiji to look for random events
- look for one-of or short term volunteer opportunities
- try new recipes
I haven't been taking my own advice very well. I'd love to hear suggestions from others. And it makes me feel better talking to another person in a similar limbo. We move to a furnished apartment in a week, and then again into the permanent house in about 11 weeks. So it'll be a while before I can get properly settled.
