Here's the finished comic. A few changes here, mostly with the rendering/painting style and some more dramatic lighting. I've also included the version for print, with German text. Here's the dialogue, panel for panel:
So that’s what’s been happening.
I’m think there’s something wrong with me
I’ve been fighting these symptoms for a long time
You have a panic disorder
Oh, is that all?
So my symptoms are real?
I’m not mentally ill, then.
