Mental health appointment

I have a mental health appointment on Saturday. I think this first appointment will be somewhat an assessment and decide the best way forward. I've been waiting for about 4 years and am nervous. My mental health treatment previous to this has been ineffective at best. 

I always worry about whether the therapist will have a true understanding of neurodivergency. They so often say that they have experience and then it turns out they really don't understand at all. And therapy being tailored to neurodivergency is so so important. I'm worried that it won't be and that this will just be another fail.

In my last appointment, which was also an assessment, they really wanted me to have a goal. Apparently to feel better is not a good enough goal. They always seem to want some huge goal like some big career move or something to be working towards. All I want is to feel more comfortable in the world. To be less scared of everything and to feel some kind of positivity about myself. To actually look forward to things rather than just being terrified of them going wrong. Why isn't that enough as a goal? I'm worried that this will be a sticking point in this assessment too and that they will see it as being awkward or not dedicated enough to treatment.
