Why does my anxiety spike out of nowhere sometimes?

Lately, I've been noticing these random spikes of anxiety that just hit me out of nowhere. One minute, I’m fine, and the next, my heart’s racing and my mind is flooded with worst-case scenarios. It’s been going on for a few weeks now, and honestly, it’s exhausting.

I haven’t changed much in my daily routine—work’s the same, I’m eating okay, and I try to get enough sleep. Sometimes I wonder if it’s just my brain being weird or if there’s something deeper I should be looking at. I don’t always have a clear trigger, which makes it harder to manage.

Has anyone else experienced this kind of sudden anxiety? How do you make sense of it or calm yourself down when it hits unexpectedly? Would love to hear what’s worked for you or even just to know I’m not alone in this.
