What should I do?

Pr

So when I ask this question idk what sort of answers I need here, just anything at all, my best friend of 11 years has been in hospital for 8 months without a trace of anything it could be. Doctors are confused about it and I just need any advice to make me less sad please. She’s not herself and she’s not smiley and she’s lost too much weight, I really need anything to make it all easier on her, her family, and me.
