I'll most definately be here for you too! I know almost exactly what you're going through... I had a bloodclot in one of my eyes that rendered me half blind thanks to me being overweight and getting a disease called insulin resistance and I too had to loose weigh and have alot of crap done to my eye. I over-did it alot though, and was just super depressed and stop eating totally which made me loose about 7 kilos a month (thats 15 american pounds), so my advice to you is to do it the healthy way like you are planning!!

Good luck on your surgery and everything else. We'll all be here for ya
