Welcome Rosie! I'm new, too. I know how you feel. My husband and I are far from any close friends or family and I don't have school for the summer so I have nothing to do. That's a lie, I have plenty to do, but don't feel motivated to do it.
I just joined 3FC this week and I've really enjoyed reading the forums and seeing how much weight people have lost. It's really been an inspiration and has pushed me to get up and get moving.
I hope you find the support you need and good luck on your journey!
