Well done for re-joining, it's a difficult step to take but like you said so worth it!
I am a re-joiner too, I left my group last September after losing 10lb due to a family emergency which lasted months. I finally plucked up the courage to rejoin last month just under a stone heavier but I have lost a stone now and I'm feeling like I am in the right frame of mind - nothing will stop me achieving my goals now.
Good luck to you, you sound like you are in a great frame of mind
