It was some months before covid, December i think. I had a big panic attack when I was alone. really one the worse I've had. 

After some time crying and being extremely anxious for some reasons, I remember looking at myself in the mirror, I was white, I looked like a corpse. It’s the only thing I remember. 

I then woke up about thirty minutes later, on the floor of my living room.  I have no recollection of what happened excepted what I just said. I took my phone I went to snapchat as a first instinct and I see in the camera that I am purple, as if I had suffocated. 

I was a little better than during my panic attack of course. I thought about it a lot and I couldn't figure out when I passed out or why. Still don’t understand what happened. And before it happens i didn’t knew that a panic attack could go this far

Does anyone has ever experienced something similar ? 
Is it normal that it get this far ? Or do you think that me passing out has nothing to do with my panic attack
