UK national adult in EU seeking adult diagnosis

Hi all,

I am "seeking"/ exploring an autism diagnosis.  All the signs from childhood, but high-functioning, and copied everything I could to mask, but now, I think it may be affecting my career and I seek diagnosis. (well, it affects my life too, but I've just rated that one as a given, haha) 

I am to return to the UK in a year or so, I live in Germany, a part of me wants to have that diagnosis before I return to the UK.

Any ideas?

Many thanks
