I have no irrational fears.
The only fear I have for my personal safety is high-powered radiation, because it's like the power of a god in its ability to wreck your shit permanently.
I used to work with high-powered radiation. I handled it stoically and with lead/concrete/steel shielding, and eventually got worn down from constantly being on high alert and being super careful of everything I did, so I quit.
Even then, it's not really fear per se, so much as it is supreme wariness.
My other fears are for the happiness and well-being of the people I love. I face those issues either as directly and relentlessly as possible, or philosophically, depending on what I actually have the potential to accomplish.
I dunno. I've sort of suddenly...snapped...several times, and each time I sort of...evolved.
One day I sort of snapped and I stopped feeling fear for myself. Dunno why exactly. Too many frequent encounters with almost certain death in all manner of conceivable forms?
Recently I sort of snapped and stopped giving a damn about awkwardness. THAT I think I understand. I spent 8 years having a SUPER awkward friendship with the person most important to me, so I built up a huge resistance to awkwardness....and then I recently found myself in weekly situations where surreal awkwardness was just pushed to new limits and treated as utterly normal....and so one of those weekly situations I reached a sudden zen-thing where I realized that awkwardness is just people feeling preconceived ways towards various things that don't really matter.
I can now carry on a 4 hour conversation about politics, conspiracy theories, religion, the origin of life, aliens, the plot line to all of the Sonic The Hedgehog games, and the merits and flaws of Marvel VS DC...with several random people (from teenagers to guys twice my age), and an assortment of naked chicks whose names I don't even know....while we're all watching James Bond or Christmas movies. That describes my Wednesday nights for the last 11 weeks.
Once you get over those sort of anxieties of whatever worries you most for your personal safety, and that people should react a certain way to certain situations...I dunno. It all seems to be a bit silly to work yourself up over something for no reason.
It's really basically just the people I love who are the focus of all my remaining concern, and their opinions are the only ones that might phase me enough that awkwardness may have a say.
