Totally understand your pain. Lost my Golden Retriever, Megan, 18 months ago. It broke me. We had to make the decision as she was very poorly. I feel for you. It's bloody awful.
I am a big fan of Oasis but so glad I didn't waste a lovely Saturday trying to get overpriced tickets. Well done all those that did get tickers, I hope you have a great time.
I did see them at their best many years ago, supported by The Verve, so not bothered this time.
