obese and depressed

The only thing that will help you is to change your perspective and the ways you see things around you. You have to be honest with yourself and see how much you can do to change things - and even more important, you have to decide if you are really going to follow your plans or not. I don't know if you have looked for any professional help with depression, but it might be a good idea, at least for a while - when you are depressed that mood covers everything you think and feel, getting rid of that would bring down a huge burden.

Everyone sees all the little imperfections of their body the one thing you need to do is ignore them. Also to make yourself happier, everytime someone does something nice for you think in your head "they didn't need to do that but the did because they care". I know life can feel sad sometimes but the thing to do is try to get past it
