Ow @Shaz51, that's hard on top of everything else.
Yeah, I'm waking up 3-ish in the morning and taking 2-3 hours to get back to sleep. My sleep was really messed up when things were so full on with Dad unwell, then dying, then getting the funeral organised. So much to deal with. And now my brain seems to have decided that it's "normal" pattern includes a stretch of way too wide awake in the middle of the night. If we're not careful, both Hubby and I end up drifting back to sleep when the alarm goes off. That's not too much of a problem if nothing much is planned for the morning, but we have to be very careful not to do so if there's an appointment, or we're heading into church or suchlike.
It really was the right time to let Dad go, and we'd had so many fond farewells and worked through so much grief already, it feels more like a sad but "right" resolution of that grief. Sometimes I'm a bit sad, but mostly grateful for the good times and good memories... But I am seriously exhausted. To do everything that needed to happen, and to spend time with some important-to-us people in the middle of it all meant pushing a lot harder than I usually would. I'm aware that my brain chemistry misinterprets "busy" as "crisis", and kicks into an adrenaline driven "push through until you get out the other side" mode, but that's physically expensive. It just takes out a lot of reserves, and it may take a bit longer yet to rebuild them. Meanwhile, smaller stressors like the conversation that nudged into painful territory pull a bit more out of the emotional energy bank, and that means it takes that bit longer to recover.
