I hate my imagination sometimes

On Sunday morning my boss' wife had a major stroke. She woke up in the morning and tried to say that something was wrong but only a slurred moan came out of her mouth. My boss asked her to squeeze his hands. Her right hand was strong. Her left hand was not moving at all.
He called 911 and it all began.
Life changed forever for them. She is 53 (I believe) and before this, in good health. Both of them are active in their church, community, and their careers. Both are very good people who love each other very much. Both will never be the same.
When I heard this story, with my jaw hanging open in disbelief, the picture in my head was of my wife making a phone call to her work. Explaining how she was not going to be in for who knows how long. Telling her co-workers that she will keep in touch and let them know what is going on later that day. Asking everyone for their prayers and thoughts. I kept seeing myself in that hospital bed with my poor wife going through all of the crap.
I could not stop crying pretty much all day. Every time I heard the story told to a co-worker who had not heard, I would see my wife again calling all of our loved ones informing them of the incident.
I felt guilty. Who am I to think of myself when they obviously need all of my thoughts and prayers right now? I could not help it. Sometimes things that hit close to home take over your mind.
I remember back about 5 years ago when my doctor at the time told me that if I didn't quit smoking within a year that I should expect to have a stroke. I just quit this year so what damage has already been done? Who knows?
The fact is that regardless of how great I take care of myself, the odds are against me. Diabetes is most likely going to kill me and probably not in one swift blow. The thought of deteriorating scares me so much.
I am not afraid of death but I am terrified of dying.
I already feel bad about what my wife will go through someday. I want to apologize now for it while I still can. Not that I expect it to happen tomorrow or even next year. But just like what happened to my boss and his wife, you never know when something like this will happen.
Let's all live each day to the fullest because you just never know.
