Malsedge,

The States idea is rest too. Specifically, you need quiet rest. That means rest where you have minimal sensory stimulation. You do not need to be in bed or sleeping. In fact, very mild stimulation to keep brain blood flow going is best. Any activity done with the hands is usually OK for light stimulation. Sewing, knitting, playing solitaire with a deck of cards, etc. Limit or eliminate screen time, TV or computer. Limit talking time, especially talking with multiple people.

It may take a few days of rest or even a few months. There is no way to predict your recovery time. If you do not get quiet rest, it will likely be a long recovery. When you start to feel better, slowing return to previous activity levels. Try increasing your activity level at home to see if you still feel good the next day. Most activity will not cause a return of symptoms immediately. There is usually a day lag before feeling bad again. This is why you need to start slow.

btw, Doctors in the States don't do much better with concussions.

My best to you.
