How to cope up with the anxiety in the IT industry?

I am a Java developer. I should admit I am a bit pessimistic and I feel like my future is not secure in IT. There is no job security. The current company is just squeezing more work out of us without giving any hike from the past few years. I feel that I should be prepared and I should switch, but the market is too dramatic these days. Layoffs can happen anytime anywhere. I feel you become more vulnerable when you join a new company you don't have much to showcase what you have done in the past. I also feel that AI/ML integrations everywhere is going to reduce head count in the companies. So opportunities will be less and the competition will be sky high. All together you are never going to live peacefully in this industry. You will always be vulnerable to new tech and layoffs. Can someone show the good side of it?
