You can work on a bakery, waiter, cleaner, sales and a lot of other jobs. Even if you are an introvert, there will be a job for you.
But I don't believe tech is going away. You better work on getting this anxiety away, you were probably thinking "oh shit, things are going down because there are too much clowns getting funding and giving web dev projects that makes no money for them and go bankrupt". I did that frequently, maybe you also did, I'm just trying to view things from your perspective.
The other side of the story is that for every 100 clowns, there is 1 that succeeds and controls a whole industry. Programming will be well paid for a while. Most of the people can't/won't even learn how to program or be willing to do it to earn a living, no matter how good it pays.
Consider actually learning other platform, such as systems engineering/mobile etc. That will definitely help you out with that.
Even if you would help people writing VBA functions in Excel you could make money. There are a lot of old people making 6-7 figures that can't open a PDF. Remember that. The economic and the system as today, isn't going away. There will always be banks, politicians and entrepreneurs creating jobs and keeping people busy.
As long as you are willing to work, you will do just fine.
