I recently moved to the other side of the world.
A couple of days before leaving we had a leaving night (excessive alcohol was consumed) and felt rather hangover the next day but continued with plans with family.
During these plans i suddenly felt like I was going to faint and despite attempts to help symptoms it didn't pass and I had to leave. On the drive home it got worse and I developed pins and needles in my hands/arms and face/neck. The driver pulled over as it appeared obvious I "wasn't myself". I tried to get out car but struggled and then the most frightening experience of my life occurred. This horrible feeling came over me and I began asking for help as both my hands spasmed up and I struggled to speak. I felt like like it must have been a seizure and managed to say this but then I was able to sit and do nothing. An ambulance was called. My hand spasms wore off before the ambulance arrived but I felt the spaced out feeling was still there and was terrified it would all happen again. In the ambulance all my vitals were fine but they noted I was hyperventilating and this is what likely caused the hand spasms. Essentially it was a severe panic attack.
I didn't feel like I was panicking, though the feeling of being faint had started to make m worry.
Since then I've had multiple, sporadic episodes of the same dizzy/spaced out feeling but have tried to deal with and have attributed to anxiety though I don't feel anxious. I'm worried that it's something more serious or am I just subconsciously traumatised by what happened...
