Shit, our terrible healthcare system's given me what'd probably qualify as clinical anxiety for longish periods several times in the last few years, and that's despite being well into the top 20% most economically-fortunate Americans, consistently having health insurance, and not having really serious or chronic medical problems in my immediate family.
Same here. I am totally terrified of being in an accident or having a serious disease and then getting wiped out financially as I have seen others in similar situations. If you are lucky things usually work out but it can easily happen that you are liable for a $60000 helicopter ride or a $300000 hospital bill because somebody (not even you) has filled out some paperwork incorrectly.
> I am totally terrified of being in an accident or having a serious disease and then getting wiped out financially
For majority of people through history, a serious accident or disease would wipe them out biologically, not just financially. Were they totally terrified throught their lives because of it? I don't think so. It's all a matter of perspective.
I personally try to accept that my life will end, the ending will likely be agonizing and nasty, and it can happen at any moment. I don't know a lot about meditation, but I think some strains of meditation schools tend to focus a lot on this fact, with daily contemplation of decaying bodies etc. It's an ancient tradition which may actually contain a lot of wisdom.
