well, there's a positive side to it... if you really want to be optimistic.
A few years ago I developed a serious case of allergy to dust, and it degenerated into asthma.
One day, at school, right after the last class, something triggered an attack, and my throat was completely blocked out, after a couple of bad coughs, which also mae me exhale all the air in my lungs. A few colleagues were there, and they really got scared... one of them thought I was choking on chewing gum or something, and started to pat me on the back, which made it worse. I was gasping for air, without one molecule of oxygen entering my lungs, and almost one minute passed, in which the pain and desperation were overwhelming, and I started to have "tunnel vision". I remember being very upset about dying in such a stupid way. It was clear to me I would die then and there.
And then, miraculously, the windpipe opened just a bit, and I was able to inhale a mouthful, trying not to choke again.
That moment changed me forever. After you face death, you look at life with different eyes, and your values are reshelved accordingly. Nietzsche said that when you look into an abyss, the abyss looks back into you, and it is then that you find what makes you a real person. a sort of childhood's end, if you wish.
I don't know if this helps, but I thought it could be useful.
cheers!
