Welcome. I want to tell you that I started at 300 and a size 26 and have lost 70 and more or less kept it off for 5 years by living low carb. I am now moving into losing the other half and have the same goal that you have. a fit size 10 at around 165 would be perfect. You can do this and once you start to see the success you will feel better and be happy about where you are headed instead of feeling depressed about where you are/were.
