There’s no point crying over spilt milk, spilt milk spilt when uncertainty abounds even more so.
You have a decision to make, so make it with the best of your knowledge at the time. Don’t blame yourself if things don’t turn out as expected. You weren’t to know.
Tough decisions or any decision for that matter made during uncertain times cannot be blamed for. You’re making the most of a bad situation, when any outcome is possible. Just take as much time as you need (have) to make a decision. Once it’s made, stick with it.
Sure things would have turned out different if you made a different decision, but they didn’t. No point crying over spilt milk.
