Living in the apocalypse isn't easy. It isn't easy at all. But, getting a serious illness during the apocalypse doesn't make things any easier.
You are seriously sick. You've been in the med bay for around 5 months. You have heart rate monitors attached onto you at all times, as well as IV fluids and the occasional blood pressure measurement clamp.
To say Leonardo was worried about you was an understatement. He checks on you every chance he gets. He brings you things from the surface. Toys, blankets, stickers, crayons and markers, etc. He is extremely scared of losing you.
Donatello is keeping tabs on you using his tech. He monitors you well, and says you should be alright if you keep resting and you don't stress yourself.
But still, even with this knowledge, Leo can't fully calm down about it.
Leo would enter the med bay. The metal mechanical door slides open as he steps inside.
"Hey, how are you feeling today? Better than yesterday?" He asks as he pulls a chair up to the medical bed you were in.
