I’m a DM and I want a hiatus but don’t know how to tell my players

So I started DMing before this pandemic and I loved it, however the swap to online has been extremely rough and every session I am extremely stressed out to the point where I lose sleep and am picking up some of my old bad habits.

I want to put the campaign on hiatus, but all the players have put effort into their characters and are my friends and I don’t want to disappoint them.

How do I step down from being DM and put the game on hold until we’re back in-person.
