Welcome to PsychCentral, salt. That's quite an experience, to be sure... and I agree such an overreaction is cause for concern, imo.

I'm not sure having a "streak" of PTSD is quite the term, but it might be something you follow up on with a T? You can review the items that result in a diagnosis of PTSD... I hope, for you, that it isn't that...

Learning to handle stress, rather than allowing the stressors to build up (which I hope is all that happened with you) might prevent such long lasting reactions.

There is alot of information on this site, both by DocJohn, and in our posting... I hope it helps you figure out what's happened. TC
