With no diagnosis you cant really get SSI or professional help. Your own methods havrnt worked. She needs an evaluation to at least point you in the right direction. If you buy insurance, it may be expensive, but she needs the help. Does she see foctors at all?
This is not normal ten year old behavior. Her not being in school is fine for typical kids but they have free services at school that you cant provide. Not to say school is diagnostic...it isnt. But its offerrs free intervention.
She needs intervention and diagnosis or, as you see, she can not get better. I believe homeschooling is usually great, but maybe not for this kiddo. She is not able to access any help from any resource and you are floundering. Something needs to change do she is not just limited to home.
Hugs, love and light. Think out all options. You may need to widen your comfort zone to help this child. Insurance would be my first priority if it were my kid. I would want her evaluated ny a neuropsychologist. Cheaper talk therapists or social workers are not legally able to diagnose. They do not have the extensive training needed.
