Hi! We know what this is like to go through. Be encouraged. My daughter goes through this many times-even now. Her heart is not the best and it affects the lungs. She can get sick with bronchitis and pneumonia very quickly. It is not your fault. Please ask the nurses for help! Write on your child's board or post a sign that you do not understand English and speak German. If you have a smart phone with internet try using Google translator. Ask them to write Everything down so you can remember it. And don't be afraid to give them a smile or hug! They care about your son. Ask if he needs or can have a respitory therapist come every 3 or 4 hours and let them work on him. He will cry but that helps to clear out the lungs. Ask if he needs a medicine to break down the mucus if that is an issue. At $1,000 a tiny vial x 2 a day, 5 years ago, it is not given readily. But it works! Ask them what the next steps are for his recovery so you can follow his healing progress.
As for you, If a plane were going down would you put the oxygen mask on you or your son first? :-) You! Because if you pass out, he doesn't live. Drink!! Eat,Rest,Walk the floor!! Ask if they can send a meal to you or if things like crackers, applesauce,jello,pudding, yogurt and fruit are available to parents. No one wants a Parent to collapse! They need you there loving your son. And it is okay to walk away and cry or be upset or to wonder what is next. God loves you. He will give you special grace and strength to care for your family.
Lastly, give your husband a hug and tell him how much you love him and are thankful for him being there.
