It's was like reading my diary! Been there, done that. Was most successful when I stopped worrying about the scale and focused on healthy living (eating less, making healthier choices, fitting in exercise, taking care of myself). It took me ages to "get it" and I made it to goal. Stayed there for quite some time, then had a few physical setbacks, some meds and now I'm looking to lose those last 20 pounds again to get back to goal. We are a food obsessed society, but with a little effort to just be healthier...you'll find yourself losing. It won't be quick, most likely, so you have to be patient (something hard for most of us) and you may have some setbacks. When I feel like just throwing in the towel, I look at the picture of me at my heaviest. I am SO much healthier now (and thinner too, but I try to focus on the health aspect). Make small changes that will give you some success. When you knees hurt less, you'll be glad you did. Exercise also helps with depression (I know it's the last thing you want to do, but even small amounts will make you feel better). And come to SP to get lots of support (at least for me, that's a really big component of any success I have).
