I've got a similar story.
My little brother almost died of an asthma attack on Easter two months after he was born. I woke up to my mom's screams on Easter Sunday and heard police cars and ambulances outside. Being only seven and it being 5 am, I somehow slept through most of the incident up until the cars pulled away. I went to my aunt who was visiting in the guest room and asked what happened and she told me. I spent the rest of the night sleeping with my other then four year old brother, hoping the little one would get better.
I was very lucky my dad was late to work that day. He woke up late and had to take a shower when he heard my mom scream after my brother's skin turned blue. My dad rushed out and helped, and luckily he was a respiratory therapist and children were his specialty. We were lucky that the police came so soon. They came back to the house around 9 am and my brother was much better. He was always sickly as a kid, and I helped with his inhaler when he was young.
I'm so lucky that he survived such an unpredictable and horrifying ordeal. Now he's 11 and runs around playing baseball and video games. His asthma went away as he got older, but he relapsed this year. He's on medication to treat it and is doing great. I'm so lucky that he survived- I was the one to name him when he was born and I would have been crushed if he hadn't made it.
So I know how you feel and I wish you the most luck in the future. I'm so glad that you too were able to overcome such a horrible ordeal and be so positive about it. I won't comment about religion, fate, or anything like that, but we're fortunate to still have you both.
