Layoff Paranoia is ruining my life

I work at Paytm and rumours are that 35 percent of workforce is going to be fired by may end. I'm definitely in the bottom 35 percent of my team as I'm in a new team and still learning the product. Even my team lead is saying that he will be fired. Now I'm confused, whether to work more or just completely stop caring about work.

I need a change. Can anyone provide leads for a backend engineer who works primarily on MERN stack and familiar with Java Springboot stack. I'm hard working and good at Leetcode style algorithmic questions
