Just talk to them
Your friends shouldn't be disappointed in you and you shouldn't feel unable to talk to them. I completely get your concern, but if they are truly your friends, they will understand.
My in-person group was similar in that the DM was very reluctant to try to DM online and just put the game on hold. I took up the mantle of Covid Online DM and have been running things. The first campaign was more of a 'getting used to online" to see if the DM would be more open to it once they understood it.
They opted not to because of discomfort with the whole system. Yes, I was disappointed not to continue our primary campaign, but I've been running games for the group online since.
Talk with your friends, maybe one of them is more comfortable with digital tools and can run a different game until you can get back in-person.
But your personal well being is above everyone else's. You need to just talk with them and let them know what's going on, how you're feeling, and what you'd like to do. You can bring up that someone else can run something online, but it's really not for you.
