Very sorry to hear your news. I can only imagine your loss. Private pilots I feel are a very dedicated bunch, investing so much time, effort and cash for no financial reward - therefore we all share passion! I understand you're desire to return to flight. Can I suggest that you try not to focus on returning to where you were before (in a P1 position) but rather just get yourself back up for the sake of getting back up. Go on a dual flight and perhaps don't think of it as an excercise in which there are certain goals to be achieved. Why bother? Plenty of time for that later. For now, I would suggest just flying again with no 'targets' per se might ease your mental burden.
You are in my thoughts and I wish you all the best.
