Weight loss

What did you have as your motivation to do it, keep going, and get through it.? I've done it before and have Since gained all my weight back. I can't really use my previous motivation again and nothing has been harder in my life. I love unhealthy food way too much and I can't find it in myself to Say no anymore. But I have also been going through depression which is partly the cause of my weight gain and at the Same time now I hate myself for being fat. They Say to work out to relieve depression but being depressed I have no motivation to do so. It is a never ending cycle.
