Is the mind racing normal in mania

My brother passed in June 2024 and his birthday was Wednesday…and I’m also going through PMS with my period being next week.

But this month is different…it feels like the left side of my brain is going twice the speed and I have a headache bc my mind is thinking so fast.

Am I going to be okay? I keep taking screen shots of advice. Doing yoga, I’m still able to work…but I’m so worried I might totally crash bc some sort of episode is happening and it’s always around ptsd flash backs of how my brother died.
