Dear Charlotte, the world is so much better with you in it.
I'm in a similar situation regarding finding health insurance-funded experts. When I was at a point where my life was on the line the insurance lady basically said, "yeah sorry, but regulations".
I found although not perfect, that Google's AI is incredibly helpful in talking through these issues and coming up with practical ways to deal with ADHD, transition questions and such (microroutines, tricking your reward systems). So while you're looking for a therapist, this can give you some support. Since it's AI it's worth noting that critical info is to be double-checked for actual merit.
Hang in there girl, you look awesome, and you're okay. Having these issues is *not* your fault.
