So the inevitable has happened Monday night at 1:30 am

Oh...my heart goes out to you.
I also had videos of one of my cat's last days & although they didn't reflect her suffering, they were so painful to watch that I finally deleted them. No regrets, I was just torturing myself by watching them. Although I couldn't bear to watch even your videos, obviously what you've created is a beautiful & meaningful tribute.
In due time, as your grief slowly subsides, may I humbly suggest you have a loved one password protect your page / site - and keep yourself out - just until you can look at it again, without as much sadness as you may feel now. Just so your grief can run its natural course.
My second piece of unsolicited advice for the day is this: It helps to know just what kind of media will bring you misery & what will bring happier memories. For me, pictures are sweet, even voice recordings of people who've passed on are touching, but for whatever reasons, videos of anyone or anything that have passed on, in good times or bad, are just too much.
