This is something that I've just started doing. It kind of silly, but it might help. I've started telling myself that I care about me. I look at myself in the mirror and talk encouraging words. Example:
Max, I'm really proud at how well you're doing.
I'm happy to be me.
You are a good person.
I will take better care of you.
I love you. Max


I've been so hard on my body most of my life, took it for granted, never really took good care of it. I took better care of my cars back then. I think it's important to let your body knows how much you care about it no matter what shape you're in. If your body knows you truely care, maybe it want to get better for you. Who knows, it couldn't hurt.
