Why do I constantly blame myself for every little thing. I’ve always been that way one little thing goes wrong or not even and I just blame myself and think I’m a horrible person why?

I can really relate. I know what it's like to blame yourself for everything. It's a horrible thing to experience. I'm sorry you have to go through this but there is a way out. I'm not saying I have the answer but I can give you a suggestion. Believe in yourself. You are amazing. Just the fact that you are seeking help is unbelievable and I honestly feel inspired by your courage and strength and I think you should too. Love yourself. Believe in yourself. Seek good friends. And never ever fall into the pit of think yourself worthless and unimportant. You are beautiful and can change the world with your beauty. So please believe in that. Don't blame yourself believe in it.
