How do I stop hating myself?

Accept what you feel. Understand that your feelings and your body are not you. Don't deny them though. accept them as they are. Let them be. I know you might think something is not fair or you should not be felling those feelings or should not look like you look, but you are here for a reason. You are given the best cirstances to learn for a given moment. Appreciate that. You was given life. Use it as good as you can. There is love around you. Every single thing is full of it. Everything is well.
