Is it normal i hit my head and now my brain is foggy

Last Friday I stood up fast forgetting I was under a low roof and just banged the top of my head hard. I have health anxiety so naturally I got terrified and kept myself awake even though it was early, I was gonna go back to bed and I was tired. I didnt have any symptoms after like passing out, feeling sick, seeing blurry, exhaustion, dizziness and I dont even have any bump or bruise. In the evening I got a terrible terrible headache but im prone to headaches and have them often so its hard to say if the bang caused it plus a relative had visited the day prior who'd recently had a bad headache.
Anyways ive been fine but yesterday I was for a walk and my mind felt so foggy and I was very unfocused and far away like not completely aware of my surrondings. Like I knew where I was and all obviously but I had to be extra careful crossing the road if that makes sense.. I have sensory issues but they're very rarely that bad unless i'm sick or going to have a migraine (im pretty sure I have migraines because ive had a few visual auras but its never been evaluated).

Today I feel mostly okay but right now I keep losing gfocus trying to focus on the screen. Its like my eyes "zoom out" . Ive never met a competent doctor so I have horrible experiences. Ive tried to seek help for my regular headaches and got the answer "eat painkillers everyday then and get over it"and thats their general attitudes. No matter what your problem is "take painkillers", because its easier for them I guess!!!! So what do you think should be done?!
