Shirley,
I know completely how you feel! My boyfriend of 5 years is having his sleeve surgery in 2 days and feel SO overwhelmed! I, too, was searching for a support group just like he has but for significant others. It is a HUGE lifestyle change that the whole family must be willing to commit to. Congrats to him on the weight loss so far!! I'm here if you ever want to chat or just get something off your chest that's what supportive people are for!! And, if you happen to find that support group give me a shout!!
Good luck and I wish you both all the best!
