HI KN,
It is a really a frightening thing to have a heart attack, and perhaps even more so for concerned family members. I recently went through this same situation when my wife had a heart attack a little over a year ago as we returned from a 2 week cruise. The surgeon put in a stent, and she has done well since. It does require a lot of life style changes and ongoing medication. she takes 4 prescriptions every day for the rest of her life and has Glycerin at the standby for emergencies.
The positive side is that she is fully recovered and has the faith that she can carry on a normal life. Therefore we took another 2 week cruise and just returned. This time all she got was the flu from me as I got it the first day home. We are now recovered from that and trying to catch up with the Holiday Season.
When something serious like this happens to a loved one, we suddenly realize our shortcomings in our relationships. This is a wake up call to renew and rebond those relationships. It may be the only opportunity we have.
We pray for your fathers full recovery and wish you and yours a great Holiday season.
