Bouncing leg can be restless leg syndrome, or simply just nerves. Even ADHD, which is dual-diagnosed with ASD more than isn't apparently.

I went in for ADHD dx, came out with ADHD and... ASD... my response to ASD made it quite clear I disagreed. Whilst I later realised I was working on ignorance of media stereotype of autism after reading up on this "ASD", I couldn't see it, read more, thought about it, maybe, but...
I had enough in the end, am I aren't I, and just said screw it, just agree so get of this merry go round.

Then, I didn't fit in on the wrongplanet forum at all. I just decided that I am one of the more developed ones. (I read a lot of personal growth stuff for years before finding out about the dx), to not lose mind trying to figure it out again. Especially with the Aspie score and the average and equally balanced systemizing and empathising, I did just before.

Well, learning about C-PTSD and such later (recently took more notice), I now think that ASD could be a misdiagnosis for that. Same kinda symptoms, and other reasons for the few parts which they'll say C-PTSD doesn't have.

Accepting a diagnosis or crossing one of the list, especially if you've thought about it for a while, is hard at a later age in life, I didn't get dx til 2 years ago at 26.
A late diagnosis in life isn't the best of things, but it's better than having the wrong one.

I am envious that your Psych, is being so thorough.

If you still feel it's correct, then unfortunately you're gonna have to prove it in a logical, orderly factual way. Or try a different Doc.

I felt guilty saying I had ASD in the first 6 months, felt like it was a lie.
Few months in after ADHD dx, I said to self, "you're not ADHD, just try again" (I failed consistantly over years trying).

The important thing is, that you are looking into it.

ASD/ADHD have a fair few symptoms of other disorders. Hell, I even asked my Psychiatrist, how do you know if you're a Sociopath. Because I had read up on ASD and some traits were similar, lol.

We certainly aren't the first people to feel like this.
Psychology itself though is abstract, and believe me, THEY make mistakes.

Hope you find out soon.
