I was Red Cross EMR certified twelve years ago, which is more intensive than their CPR training [though you learn CPR as part of the course], and in my course they tell you re: CPR straight up, "This is not the movies, it might not work, but you still need to try." And let me be blunt, doing CPR correctly requires strength and stamina, which I no longer have [why I haven't gotten re-certified]. I was fucking exhausted when I practiced CPR, and I was in somewhat better shape than I am now.

So yeah, CPR is a crapshoot but it's better than nothing.

I unfortunately have no resources for retraining uncertainty tolerance but also like Sabotabby I have a strong resistance to acting different without feeling different. Also, I have the kind of life where I can get away with avoiding a lot of my triggers [but not all of them] like frex I'm very claustrophobic and freak out in elevators but I rarely, rarely, rarely ever have to go in one and usually if I'm in a situation where I have to use an elevator it's also a situation where I can get away with being sedated in public with friend looking out for me. That sort of thing.

I'm sorry the lockdown confinement is so hard, that really sucks.
