My Boyfriend Has Been On Life Support For 2 Weeks,

My boyfriend has been on life support for 2 weeks, my grandbaby was born last week and had to stay in hospital needing additional oxygen and antibiotics but he's good and home now, my son came to visit my boyfriend in the hospital yesterday and passed out and they took him to ER and checked him out and all vitals are good and blood work came back not showing anything is wrong. Recently I am beginning to experience lightheaded, and I hear everyone around me talking but it sounds muffled like water in my ear and feeling a little nauseous and faint or weak. When I sit down, I feel better, but still feel not quite myself.
