Is anyone afraid of the future and not being able to get their medications?

I live in the US and I don’t know if this is an irrational fear but I’m sort of afraid of the future. Like if sh** really goes south here and something happens with healthcare or I don’t really know what. Like an apocalypse. I just have this fear that if I’m alive in 20 years, I might not be able to get my medication for whatever reason and it really makes me nervous.
