We have extended our break from foster parenting, and may make it longer due to some other things we have going on and the time and money taking in more kids requires. In the meantime, we continue being part of our new (reinstated) local foster/adoptive group, the G.C. Foster Care Association.
If you have a local support group, go to the meetings if at all possible. If you don't have a local group, consider starting one or traveling to the one closest to your home. The emotional and other supports your will get (and give) are well worth the effort! Fostering is a hard road and it often feels like you are walking it alone. I'm lucky to have a couple of other foster families in my church, and that helps a lot.
If local or regional groups just aren't an option at all, you can go online for support. I blogged about my favorite foster/adoptive blogs to go a few months ago. I have also mentioned a foster care forum when I talked about what every foster parent should know. Reading and getting to know other foster parents online is a good substitution for real-life support. You just have to be even more careful not to use real names or identifying information about anyone involved in the situation, especially the children themselves.
Another place that I've been surprised to find some kindred souls is on Pinterest. I have my own foster/adoptive info & blogs board, and am following several others in that category. Here are a few of my favorites!
The Dave Thomas Foundation
Then there's Facebook. Most of the people who use Pinterest or have blogs also have Facebook pages, some even have interactive groups. I'm not members of these, but here are some I found.
