Can you show the source of your investigations? As stated here, or in reply to your other post, exit door seats tend not to have windows, and the first layout of A380s didn't even have an 80A and 80K as the escape chute in the door protruded too far into the cabin. A re-layout moved all the rows from 80 and up back a bit so seats 80A and 80K now featured and it seems likely that they might have part of a window as kq747 says. All 2 class planes have the newer layout described so you could be in luck.

Without going into too much detail, what are the other conditions apart from anxiety you have that mean you require extra legroom seats? With some knowledge there may be alternative solutions proposed.
