Thanks for the answers people!
I can go to an emergency room, but it's just a primary attention center (since i live in a small town), so i don't think they'll do much >.<
I could go to the nearest hospital but my parents say that it's just stress and that i should go out more s:

What scares ne most right now is that the doctor appointment won't do much since he will only send me to a specialist (which I'll have to wait months until he visits ne), and the studies are gonna be harder than every this year... so I'm afraid i will just fail with my brain all foggy..

And when it comes to falls and hits, I haven't received anything in years, i don't smoke and i don't drink either.

I just remember that i went to visit my grandma, had a perfectly normal day, and when i went to sleep that night a panic attack showed up. My mind has been feeling "foggy" full of stress, anxiety and just more dumb than usual >.<
