Thanks everyone for your kind words and advice. It really means a lot to me right now. I hope someday I can get over this and turn it into a lesson, and I will share what I learned so others can be more careful.
To @dang and the moderators: I honestly do not understand why this topic was flagged. This situation is real and very painful for my family, and it is beyond my imagination that sharing it would be a problem.
Sorry for any distress over this. The moderators didn't flag (or see) it. Users flagged it, and whilst we never know why users flag things, in this case it may have been because it seemed outside of HN's usual scope. But as moderators we think it's fine if the community is able to discuss a topic like this and provide meaningful advice and help. We're really sorry this happened to your family, and we wish you well in finding a way forward.
Thank you, @tomhow. The quick response and the welcoming attitude from the moderators are something I personally appreciate a lot.
As I mentioned before, HN is a technology community. I hope that one day I can share only technical topics here, so we can focus the discussion on technical matters. I hope we can stand together as engineers, doing our part and taking responsibility, even if that does not fully address the root causes.
