I know someone who's had to go into quarantine 3 times already because their coworkers have tested positive, luckily they themselves didn't contract it any of those times, but just the stress now of having been in quarantine for over a month during this, having to take time off work, worrying about whether they brought it home to their family hasn't been good on their mental state. This person's been real down for months.
