First time dad in hospital with little man

First time dad here, my baby boy is only 4 days old and we went to the er after we heard him breathing slightly weird. We arrived to the er and they took his temperature and he had hypothermia. We then stayed at that hospital for a while and then we were transported to a different hospital in the city using an ambulance to run extra tests. Right now as I type they are getting the things together to do a spine tap for Meningitis. Wish I can explain more but i’m running on barely any sleep and i’m very very stressed out. Just asking for some support during this time as I really hope nothing is wrong with my baby. Very scared at this time as i’ve never heard of other people in my family or anyone having these problems with their newborn. Just want my baby boy to be okay. 😞
