Thanks for answering! I am just getting so frustated about wasting the whole exchange year. How can it be that someone hit in the face and losing conciousness is feeling alright after one week, why am I still stuck in there just because of hitting a freaking ball. Because I did not rest enough or what! Every day I am waking up with the same symptoms and no one is believing me and my teachers are getting agressive an let me do all this test at once(I still have to catch up a lot from the 3 weeks I missed school).
But thanks a lot for helping me!
