Jo you are such an inspiration to us newbies on here.
You've done tremendously well with your weightloss so far and god knows it's not easy to stick with long term.
I don't know your story well but it's sounds as if you've had a tough time with the job loss etc.......
While to sore to move ( lol) is it worth taking a couple of hours to think back to where you were at the start? What were your goals? How did you feel then compared to now? Can you do another measuring session/ photo shot of yourself to remind you how fantastically well you done? When I did this I lost 13st...... In my ex partner!!!!!! Lol but sometimes it's not always you/ your body that's making you feel low.
While I understand the loose skin bit it's got to be better than the solid fat version!! And it will continue to shrink long after you finished your journey.
Have you considered bellydance??? Seriously, I am a bellydance teacher and the difference I see in womens self esteem as they learn is phenomenal, it's fab exercise but fun too!!! The dancers come in all shapes and sizes and you don't have to show your belly!!!!!
Failing all the above, if you're struggling so much, maybe it's time to look at what other food plan would suit you.
Whatever you choose to do your still on the path to where you want to be!!!
Lots of love Rach
