Medical cost of gastric sleeve operation.

This is a hard story to tell and one that most won't understand, I have suffered with weight issues most of my life, I grew up feeling like the ugly duckling in the family, I was told as a child that I was a mistake, I was told that hot baths and a bottle of gin didn't work in getting rid of me. My mum left home when I was 15 and my father drank to cope with life and I ate and have continued to eat to cope with life since. I know that having weight loss surgery is not a miracle cure and I know that half of the battle for me is psychological so counselling is also needed. I am desperate for this surgery because my health is starting to suffer (I have back problems and a high cholesterol count) and mentally I suffer, I am currently unable to look in a mirror have photographs taken because I can not bear to see myself in any form. After yo yo dieting all my life I know for me to continue moving forward in life I need this surgery. Please hel
