The market crash is a big blow to a lot of people. So many people have lost huge sums of money. But killing yourself or committing suicide during this time is not an option. Just remember that any amount lost can be made in the future, but we only live once.
They lost because they lack patience ... Also, several times I did wrong, I bought and sold wrong ... As you watch the market even when the price falls after some time and so it returns to a good price. All you have to do is wait, unless you bought a BTC for 20k $, then it's a problem...
