You have a heartwrenching story. I do understand the feeling of wanting to give up. This torture goes on for years, it seems that most of the health care industry, insurers and even friends and family are fighting against appropriate care. It seems there are few success stories. I totally agree - you are not a failure as a parent. You sound like you have poured all of yourself out into the bottom-less pit of PANDAS. I hope that you can find some rest and comfort in this time and that your daughter can one day find recovery.
