Please make duaa for my brain health

Assalamu alaikum everyone. My brain hasn't been right for months now, every day a new headache that just won't go away. I try to explain, but people just say it's anxiety. I really miss my old, healthy brain. I need to study, and having it back would be amazing. Please, make duaa that Allah restores my mind. Jazakum Allahu khairan.
