I'm sorry. This sucks. This is the kind of thing you don't realize, until it happens, that it feels different when it's your town, your community. I'm queer and originally from Orlando. I flew back to Orlando after the Pulse shooting and I'm glad I did. It's kinda like tent poles, you're going to be stronger leaning in together supporting each other right now. Log off. Stop refreshing websites for the latest update on the tragedy, the facts will always be there later if you find a compelling need for them. Go spend time with friends and community right now, go join a candlelight vigil or similar. Your whole community is grieving right now, it's healthier to go join the people who are experiencing the same thing you are, support your friends and they'll support you back. Protest for changes so tragedies like this are less likely to happen again in Czechia, if that's your thing - and at least your protests might actually change things.
