Thank you both for your replies.

No I am German. I once talked to a doctor when doing psychological assesment, who at least stated that my struggle could be due to the concussion, but he never included this into his report. As I am still under 18, you might probably not be able to get an appointment at his office, as he is into pediatrics, nor did I try to get another one for myself.

I know of a center for headache in Munich, maybe you could try to get further help there.

To be honest, I am a little bit concerned to also have got Chronic Fatigue Syndrome now, as I am in the 6th week after initial infection and still feel bodily and mentally very exhausted. I still sleep very long hours and now do real breaks in the noon, where I fall asleep, which I before was never able to.

Does the same also account for you after an infection.
