@MilkTrayLimeBarrel - I understand how you feel. I'm not crying but only because it will mess up my vision and I have an assignment to write.
I do feel very sad about everything that is unfolding. I said on a thread recently on here, that I feel homesick for a world in which this didn't happen.
I think this grief is a perfectly normal response. If it's really affecting your functioning though, consider seeing the GP or seeing whether you have a friend who will sit and listen to how you feel. This thing is a big shock and has seemingly come out of nowhere. Even though we were perhaps long overdue a pandemic of this magnitude, it still feels sudden and frightening. So be kind to yourself.
