So it's been three hours now since i replied to the text. Which is where this all started. I'm now almost fully back but i still feel shaken up.
I'm not doing weird 'rituals' or shocked and dazed.
And the best bit - breathing more or less normally.

That was the nastiest bit - i couldn't breathe. Every breath took so much effort to draw in and it would shudder. Like a mountain range instead of water slipping through sand.
That was really full on for 1hr30mins.. struggling to breathe.

I lost the power of speech too so i wouldn't have been able to call someone for help.. and i'm alone in the house currently.

I really wonder what that was.. and hope it never happens again.
