i don't know you Stuart but i know how you are feeling at this sad time, 3yrs ago tomorrow i had to have my Tigger PTS, it was the hardest decision i've ever had to make, within that time i've lost my brother and sister-in-law just two & half yrs between them, all i can say is this----you don't get over it, you just learn to live with it, which is what i have been doing for 3yrs now.
R.I.P. Olivia, run free on the bridge
