So, I rode today! First time since last April.
It was fun, it was short (only about 15 minutes saddle time) we walked and trotted and turned and whoa-ed and it was all rusty and awkward but right at the same time.
My little mare has really calmed down a lot. Today is Monday, and I'd only just groomed her a few times in the last week - no longing or handwalking yet we still had a nice quiet first ride back. Felt good.
