My feelings are with you both. Going through similar torture at present, (although she wasn't a PJ fan) and I thought at my age I'd handle it better, having been 3 thru long-time loves before, but it is yet another scar on the heart. I slept for 2 days, was walking dead for a few days but I realise life goes on, however painful and empty it seems for a while.
One thing I do know for sure is that time does heal, and hopefully you'll feel like I do about my previous loves - as I remember the good times we had, not the end.
You'll be fine I reckon, as you've taken a positive leap already by posting this....and I thank you both because it's helped me too!
Surrounding yourself with people is the way to go, do things you love doing, throw yourself into work, if possible, just keep busy. Live moment by moment for a while if you wish, as I did, look forward and eventually it gets easier.
