One of my parents is hospitalized and has been for a month. Due to the nature of the accident and the slow pace of recovery (and likelihood of passing early on, which has thankfully reduced by a lot), we've been keeping the information about their state limited to close family only.
Now they're recovering, but are in no state to be visited (doctors have advised us to keep rotating visits between a limited group of 5-10 people at most). Their recovery is likely to extend itself to a year at least and there are likely going to be side-effects affecting personality, memory and speech.
I've got their phone and I know some of their most beloved friends and friends from work have been starting to wonder about not hearing from my parent for so long.
I want to let some people know about my parent's inability to get in touch with them (2-4 close friends), but I also don't want to share any medical details, neither about their accident nor really about their prognosis yet, as it has a lot of time to progress and change. I know they will probably be able to make a guess about the accident
How do I keep it short, within a text that makes them understand I write to them because I know my parent cared deeply about them, but can't get back to them right now nor in the near future (couple of months at least)?
