I don't know if leaving was your choice or not, and I'm sorry if it wasn't, but it sounds like it was a good run, and not many of us are in one place for that long nowadays, either. Hopefully you'll find something that fits you well at this point in your life. It seems like an opportunity to think about what you'd like to do next.
Are you going to stay in Ireland?
I wonder if Igalia is hiring (I'm pretty sure you know people there or used to).
I have no idea off-hand what SUSE has for openings, but it might be worth taking a look.
Good luck, whatever you decide to do next.
