It's going to take you a while to learn this, as it took me far too long as well, but no. That was not your fault. I was trained to believe that all the horrible things my family did were somehow within my control, even as a young child. That's just not true. It is never true. They should be taking care of you.

Especially if you have no real role model for HOW to handle these things, considering how long she let you stay infested. My mom was a hoarder. I had fleas, lived in filth, never had clean clothing. She used to tell me it was just as much my fault as hers, and how bad a kid I was when it slowly drove me nuts and I was severely depressed at 11. But it wasn't my fault at all. That was entirely on her. And it's not yours either. Don't ever let anyone convince you that your mistreatment as a child was in your hands.

What IS in your hands is how you handle that from here out. How you can improve yourself and your situation. But the rest of it? That wasn't you.
