I don't have advice, but I can relate. I have not been "officially" diagnosed, but my therapist has hinted at it, but won't put the 'label', if you will, on it for exactly one of the reasons Maranara described, insurance. I guess benefits stop quite quickly with that diagnosis, from what I gathered.
She is right, you are welcome here, I felt like I was intruding at first too because of no diagnosis, but no one judges here for that at all...at least in my experience here.
I have learned a lot by lurking about and I do post here now and then.
