Hi Sonja,
I think you are still in the race. Maybe get some help from a support group, a nutritionist and maybe a counselor who specialises in food issues (addictions, disorders, bariatrics).
Do you have a Curves near you? They have a super super circuit and weight management program that is fast, fun and safe. If not, find a place you feel comfortable and start getting some exercise if you aren't doing anything. Find something you enjoy.
The band is only a tool. As you know, any weight loss surgery requires a life style change. It doesn't cure our mind.
Hang in there!
