Ok, make it slightly easier. What do other people like about you?
If there is anyone you feel really comfortable with, ask them! Don't dismiss anything they say, thank them and then write it down somewhere. Maybe keep a blog if that helps to get all your feelings down.
Try talking to yourself as if you were a stranger, what sort of respect would you give to someone else? Why does everybody else on the planet deserve respect except you? How many people have you killed lately? Or have you been microwaving puppies again?
I'm finding the first few days being back in abstinance really tough going, so I'm doing it in a third person way, almost as though I'm playing The Sims instead of being me. I find it odd I would treat a pixelated game character better than myself!
I don't know you at all but I can tell you two good things about yourself straight away. You're insightful and intelligent, and you've got a lot of will power. I bet if you went back to yourself a year ago and said 'hey, this time next year you'll be 4 and a half stone lighter' that other you wouldn't believe it.
I saw a quote that really struck a chord with me, might with you too.
Don't find yourself, define yourself.
If it helps, think about qualities you would like to have but don't think you've got, and work on them. What one thing can you do differently every day that would make you feel better? Something really simple and achievable, maybe do a bit of exercise every day. Even just spending 10 minutes doing sit ups or going for a brisk walk.
I'll practice what I preach too, we can be self-esteem buddies
