Sounds about right haha But yeah nothing wrong with you its just the circumstances. First time I took mdma I almost freaked out in the sudden come-up and if you track the things going through my mind it was shit my heart is propably weak, shit i took too much, damn i don`t even know if this is laced etc.. I was alone too and I just stopped for a moment, said am I actually going to stop panicking and dial an ambulance, I was like naah I`m okay
But there, I grabbed on the idea of calling for help which chilled me out from all those paranoid panic thoughs, if I were in a dark alley somewhere alone with my phone out of battery it would of been major panic! Had a great night that night actually xD
I`d retry it for the hell of it, get really high and laugh at what you did last time
I`d totally do it, walk around in your room saying I can`t breathe man IMA FAKIN DIEEE
