L.,
You haven't said what your religion is, but I'd start there - I just love the work I do through my church & the friends I've met there. Or if you're not religious, what is your passion? What do you love? Figure that out & go for it - do you love animals, then volunteer at Willowbrook Wildlife Haven or be a Brookfield Zoo Docent. There are so many places that need help and you're looking for something to do. It'd be great if you could figure out what would give you some fulfillment. Also, check with your kids' school, they often need moms who can re-shelve books and be library helpers, and help with other things.
Good luck & I sincerely hope you find something that will satisfy your longing.
