Thanks for all the answers! My new host fam, I changed two months ago, is aware of the concusson and all the problems being caused trough that but I did not tell them about the aniexty problems. They think I can handle it really good. They also went to the neuro with me. I ended up crying there and told him that I am scared. He tried to calm me down and told me that it would go away but that did not help. I just think about hundreds of reason that it could stay forever.
My parents at home think I am too anxiuos and should stop with that. They also think it is just something I am imagining. They are not really helping either. I am afraid but I won't be able to go to a psychologist here. It's too expensive.
My dad wants me to break up my exchange year. I still have 6 months left here but if that would make things permanent i would of course rather go. I think I will meet up with my athletic doctor this week. But i do not tell what to tell him. It's embearissing for me and I feel weak!
