Howdy, Bev!

!!
I can completely commisserate with you on not owning a scale and then gaining weight without having a single idea how much.
I hadn't weighed myself for about a year. I knew I gained weight, but had no idea how much. The last time I weighed myself, I was around 130 pounds. I knew that I was no longer 130 pounds (hardly any of my clothes fit

), but I thought I was probably around 145 or 155. Everyone told me they thought I was within that vacinity. I thought to myself, "Ok, I am bigger than I'd like to be, but I am not by any means fat" until I stepped on the scale at Publix and saw big ol' 180 staring back at me

I freaked out and told myself that number could not possibly be accurate -- how could I weigh as much as MY DAD??!?!?!? I denied the big number for a month or two more, then faced the music, bought a scale, humiliated myself by telling everyone I weighed 175 (180 with clothes and shoes but 175 without), and then proceeded to change my life.
Are you able to do any form of exercise now? are you seeing a physical therapist?
Also, feel free to post in the Dieting With Obstacles forum -- there are several others there with varying degrees of physical limitation who are successfully losing weight.
