I agree with both sides as being possible, depending on the circumstances.
If I know someone who is still whining about an ex who broke up with them, well after the fact, I honestly feel they need to drop it, for theirself, and anyone who has to hear their lamentations. Even if this ex decided to take them back, who wants someone who already dumped them once?
If you lost your business through some uncontrollable situation such as the mandatory shutdowns, and now your home is at risk, this is not something to get over. It is something to address, and worry propels one towards solution, to some extent.
