How can I be there for a friend I know online?

I’m American and she is English so I have never met her IRL.

She is very sick at the moment.
She has auto immune issues and has issues walking recently.

It bothers me that I can’t physically help her; I ask how she is doing and send her nice messages that she tells me she appreciate.

I told her I prey for her health even though I’m not super religious.

Anything else I can do?
