Everybody should be terrified and cut expenses RIGHT NOW: don't buy a fancy car, pull the kids out of private school, cancel vacations, don't buy a house, don't enter into any kind of commercial lease (you'll find plenty of cheap leases).
If you are into consulting (front end, back end, ML, devops, ML) offer to cut your rate 50% if you can get a 12 month contract, right now.
Don't blame the virus. Sure it does not help but a lot of startups were barely viable businesses under oxygen (=VC rounds, always looking for dumb money for the last rounds). Don’t be picky (I don’t like the office culture, the market you are in, etc)
As they say get a mortgage, you’ll start enjoying your job better. Get several kids and you’ll start enjoying your boss/the founders/the market your startup is in as well.
