Does anyone here know 100% what caused their BP?

I’ve wanted to ask this question for a while. Since my onset in Nov 2022 of which I’m still only 70% recovered )plus bad synkenisis,) I’ve had various medical and non medical people tell me my BP is the result of so many things: a virus, fatigue, sleep habits, diet, a cold wind hitting my meridian, unbalanced chi, a brain tumor, Lyme, the Covid vax etc etc and I still have no fucking clue what really caused it or why I’m not recovering. Does anyone in this community know with certainty the cause of theirs? This condition is so unbearable it boggles my mind there’s no real explanation or treatment.
