So I know this is reddit and we are all makeshift scientists but I just wanna know if anyone has experienced similar to what I do.

Basically awhile ago, I had a panic attack/anxiety attack and fainted. Possibly a mini seizure but not sure. When it happened I had pins and needles radiate through my body towards my head, started phasing out of consciousness and passed out. Eyes rolled back and started gargling but no other evidence of seizure. At least not significant. Woke up heavily sweating and threw up. Went to hospital and everything came back clear. This was years ago. 

Today I had a panic attack/anxiety. Started getting pins and needles felt clamey and my ear went funny. I shouted for someone and they helped me calm back down and I'm fine. 

Both were caused by fear about similar medical issues. I just wanna know if I'm alone with these symptoms or if there's anyone like me and they have suggestions. I can't keep living in fear like this. 

Thank you Reddit ❤️
