Long story short. I cant imagine this happening to anyone

Over Christmas my babyboy (7months) got sick with a simple cold. We tried our best to get him to feel better by keeping him inside, humidifiers, vape baths, lots of disinfecting, ect but being that we have a 5 year old in school and 2 year old in daycare nothing seemed to work. Dec 31 comes around we had family over being we didn't want to take him out. About 2am Jan1 he gets a fever of 101.3 out of no where! we gave him medication it went down about 3:45am he gets up screaming we calm him down a bottle and back to bed not even 30 minutes later hes throwing up everywhere. We get him cleaned up and back to bed. As I go to lay down I look over and hes having trouble breathing so I sit him up it seems to go down so we all go to bed. Next day his breathing off I keep telling dad im scared he tells me im over reacting but I still take him into the ER they tell me he has broncitus and there nothing they can do and sent us back home. I couldn't sleep all night watching him breathe, next morning I call his doctor explained everything and they ask I bring him in. When we arrived his oxygen was at 82 they rush us to the ER. He gets oxygen, iv's, blood work done, everything. Hes oxygen levels aren't raising so they rush us up to icu. They start putting tubes down my babys nose trying to suctioning him, then down his throat. I'm sitting in a corner in disbelief. Everything starts to settle down and I can finally talk to a doctor I explained what had been happening in the past few days and they tell me hes not doing so great, that night was horrible. I prayed the next day would be better and things just got worse and worse till they asked me if I wanted a chaplain to come up and pray for my son. My heart dropped at that point I lost all Hope's. My baby face we swollen, he hadn't moved is 48 hours, he was pale as paper and I looked around and all I had was my mother. No dad, no family no friends. I didn't know what to respond to the doctor. I had no words but to tell her I dont care what you have to do but my baby needs to get better. I had to emotional disconnect myself from my son so I could allow them to do everything they had to even if it hurt him. My son went from crying from the discomfort of them strapping him down do give him treatment, blood work ect to not being able to fight them any long. My babyboy was weak and there was nothing I could do but lay with him and oray that everything would be ok. I felt like they was torturing him but I understood it had to be done. He spend a week and a half in icu and 48hours in observation. It was never confirmed if it was bronchitis. They tested him for RSV and it came back negative and the doctor informed me that if it was bronchitis the RSV testing should have came back positive. Unfortunately my son was discharged and I was never given a diagnosis but I am looking for a second opinion. When we got discharged everyone was calling to come see him at home and was called unreasonable when I said no. No one was there for my son or myself when I had to make to hardest decisions of my life. I'm emotionally F*CK UP, I almost lost my son and I don't know how to get over the fact that not even my husband was there because he couldn't "deal with it" I left the hospital with an appointment to see a therapist and hopefully get back to myself. I know theres moms that have been through worst but you just never think that could be you. I pray for mothers going through something similar or worse that baby and you get better.

Sorry for the long story and thank you for the ones who read this far. I wanted to add pictures but he looked so swollen he didn't look like himself.
