So sorry for your loss, life can be cruel. As someone who has lived in your shoes, I suggest you give it more time before making such huge life change (I believe they said give it a year or so). I was given the same advice when I lost my wife and I listened. I am still in Florida. 20+ years later (though It will never be home).
You didn't say when you left WNY, how long have you been in Florida?
