Even if they were afraid of coronavirus it wouldn't be so intimidating to give to your life an end to this.
Maybe economic or social reasons might be the main reason and coronavirus another one.
I'm going to lean towards the fact that a lot of people who were suffering from mental illness (think Depression) are going to be having a bit harder of a time now. Imagine being able to at least go to work and socialize with some people, see your family,etc -- now all you can do is sit in your apartment and talk to people on the phone? This is a rough time for people who were having issues before this, and don't really know where to turn to now get help. I know you can do some therapy online (I'm pretty sure this is the case at least) but I'd assume that's not the same.
Economic fears are going to be pretty bad right now. Imagine already being poor, living paycheck to paycheck and working at some sort of low paying job (maybe McDonalds) and then you're unable to pay the bills, have no idea when you're going to be reemployed, money from the gov is gonna take weeks.
Plus Trump admin is estimating 100-240k US deaths.
