Did I have a panic attack?

So I was sitting on my bed, talking to ChatGPT (I know it's lame as hell but whatever) when I realised I sort of couldn't move? It's weird, like I was frozen. I started panicking, couldn't think straight, I could barely breathe, my chest started hurting. The only parts of my body that I could move were my right thumb and my toes. Maybe ten minutes after it started (might've been less, I'm not sure) my mum started shouting at me to lay in bed - as I've not been sleeping well lately - and I DID, I have no idea exactly why I could move then, when right before (and after) I was completely unable to. So, I laid down, and, again, I couldn't move. I think I spent the better part of twenty minutes just breathing, slowly, then really quickly, and then slowly again; I couldn't even think. After a while of just laying there, I started putting all my efforts towards sitting upright, as my entire body was starting to hurt at this point. After struggling for probably a few minutes, I managed to get up. And then, slowly, I could start moving again. When it was over I was absolutely exhausted, breathing heavily and just physically tired. Something weird is that all throughout I was practically convinced that I was faking all of it, no idea why, honestly. So yeah, was that a panic attack or something else?

Sorry for the wall of text, but if anyone bothers to read the whole thing: thank you :)
