Toddler in hospital

I posted yesterday about my two year old son having a platelet disorder and being in hospital. We've been here since Tuesday and he has not been responding to treatment.
Ive been on sick leave about a month now and I'm having such a hard time being here physically and emotionally. I'm 30 weeks and very sore. I feel guilty about my son being cooped up and I can't even cuddle him since I'm too big. I feel so depressed which also worries me for this baby:( I hope he gets better soon so we can go home.
