>>804638In PR work, they teach you that the way to handle something that breaks your flow is really simple.
1. Acknowledge
2. Sympathy
3. Redirect
So for your example, the correct response is "Thank you for your superchat! I'm really sorry to hear that you're going through that. I hope that I can cheer you up a little!"
You thank them for the superchat. You express sympathy--which you hopefully mean sincerely, because obviously it sucks--but then you move right back onto the topic at hand and continue.
This is only for general streams, though. If you have space to talk about it (i.e., a superchat reading stream) you should feel free to switch the tone around, address it in a little more detail, and then switch it back.
Just remember that you aren't a therapist or anything, so don't give affirmative advice. For example, instead of saying "Do X, Y, Z" say "I found that X, Y, Z helped me in (similar situation)."
You don't want to be liable for giving bad advice, so speaking carefully from your own perspective is important. Anything beyond that, you just have to trust your viewers to find the useful parts of your experience and apply them in their own lives.
Good luck fren.
