I got my PPL(A) in my late 40s after around 90 hours. Like you, I found it much harder than I expected, and it took very much longer than I'd anticipated.
All you wrote sounds fine, except for one thing... Solo at 24 hours, but solo consolidation ever since! No nav, no instrument flying, nothing to give you a change of pace and a break? Weather conspiring against you after a pretty good summer?
It could be just that that's the way things are. However, a change of airfield and/or instructor might just get you out of what sounds like a bit of a rut. I know about those; I got stuck in several of them, and sometimes all that's needed is another point of view.
As Genghis said, learning to fly takes longer when you're older, a little fact I fought hard against, but (with a few lucky exceptions) it's true. But if you're stuck on the same exercise for too long, at any age, something else needs to be tried, not because anything is necessarily wrong, but just because it might help.
