Honestly I know exactly where you are coming from. While everyone here has given some great advice, including therapy, it really only treats the symptoms of an environment that you can't easily change on your own.

Interviews will only get worse, on-the-job performance will be even more demanding than the year before, and we're going to be expected to work insane amount of hours since we're classified as exempt employees. We might even move fully towards a gig economy, where the standard will be contract based employment instead of full-time work. We can already see trends happening:

- politically, unions have lost a lot of bargaining power, having been eroded throughout the years through various ways

- workers in general (non-tech included) are being put under tremendous strain. We still have it somewhat good for now, but it's gonna catch up to tech very soon, if it hasn't already (ridiculous ip/non-compete contracts, non-paid overtime at night and weekends, agile micromanagement, stack ranking, etc).

- We can see our responsibilities increase as a techie, but not very much our pay relative to upper management (again, same for non-techies too): we went from separated roles of backend/frontend/devops/database engineer -> full stack engineer -> cloud/aws engineers. We now need to know 10x more and manage basically entire product pipelines individually as the starting point of an engineer.

- Discrimination gets a free pass in all industries, just see all the sexual harassment, ageism, 'cultural fit' based environment that has become standardized.

- Losing your job with no safety net means no income, no health insurance. Not good for your overall well-being to have this implicit threat hovering over you constantly.

- Free time is decreasing, and we feel it. Weekends are no longer about relaxing or exploring new places, it's catching up on more work like chores around the house. And because of this, we're pretty much stuck in our place of residence since there isn't much time to do anything else. And on those 3 day weekends, prices for everything (hotels, flights, etc) are insane and very busy, making your exploration time kinda negative and increasing your anxiety even more.

- Employees getting screwed out of startup valuations or stocks with financial trickery, or just outright theft (because it's costly for us to sue individually and class-actions are not very effective in dishing out punishments).

And so on... The real answer to the constant anxiety like you and many others (including me) experience is from the overall environment that we are all in; it's getting worse and the reality is we can't escape it. Our politicians don't really care for us, even our own techie brethren don't care (just see how divided we are on unions if a single construct of it is corrupt, despite the situation we are in now which is total power to the employer).

I feel like if we solved our environment, all our anxieties will be lifted, as a permanent solution. That, or just be really rich by having the right connections or just use all your free time and joy studying to become the best of all of us (latter not guaranteed if you don't have the right social skills to climb the latter). All we can do is wait for a martyr to initiate the process of improvement and we help back them up. But for now we can seek whatever tiny joys is in our lives and use it to drown out the truth of the environment we are in. We have to lie to ourselves.
