I also struggle with self-hatred. I've had it for a long time. When I was a teen I specifically paid attention in class, when we learned about anorexia, to learn how to not eat so that no one would notice. I believed that I was not deserving of food, and would purposefully starve myself. So, I've been there. It's pretty much a form of SI (self-injury) which I also struggle with.

I don't hate myself quite so much any more. I still don't like the way i look or my body at all. I have this weird thing where I have a different mental image how I look, to the point I dont' like looking in the mirror, because it doesn't look like me. But aside from my appearance, I've come to find things I like about myself.

I'm a good singer. When my brain is working I'm actually a decent writer. I'm very creative and artistic. I'm funny. I'm caring. I'm smart. I'm important to my family (my husband and kids and mother-in-law.) And so on...

So, it's good to list those things. You already started. You're intelligant and analytical. Those are good things! Every day try to find one new thing. Write them down. But don't put them in a journal. Like, hang one on the fridge. Put on on the bathroom mirror. One by the door before you go out. Just put them around and read them outloud to yourself.

I know it sounds silly, but it does help.
