Sounds like you need a huge break. Why not get someone to watch the kids and go with your husband on his next band thing. Will your or his parents watch the kids for a weekend? You have to take some time for yourself. If you can't do a weekend or the band thing, see if someone will watch the kids for a few hours and go get your nails or hair done, go to the local Belks/Hechts/Dillards and get your makeup done at one of the Clinque/Estee Lauder counters for free. It is a great way to treat yourself and feel better. If you want to find new friends locally, try going to meetup.com and look for the ex jw group in your area and see if a few of them want to meet up one weekend. You can choose a family friendly place and take the kids with you.
