@Mary-12,
No one can answer this sort of complex issue on the internet. Lay people do not know and medical professionals will not answer.
In truth you need to go back to the medical professionals. Obviously your child requires psychological counselling to ascertain what the issue/issues truly are.
Posting on here or indeed anywhere on the internet/social media achieves less than zero, it is simply wasting time .... However every day your child grows older with this issue, the worse it becomes for her.
Get professional help for her.
Sometimes with the medical profession one has to kiss many frogs until one meets the prince or princess required. Your daughter has an issue which will very soon (if not already) become an extremely serious social problem for her, let alone the toll it will subsequently take on her mental health ....
So, you have to keep pushing until you find proper professional help for her.
