I like your plan for tv and rain-listening also. i have always loved the sound of rain personally.
the mess is temporary you will get on top of it when you are ready. sounds like you need a good bit of rest. i'm glad you have such a good group of understanding folk in the AA group.
i hope you manage to have coffee with the guy you met that you may have coffee with who also has TBI w/PTSD and a service dog, and that you can learn some stuff. without weird fraternization complications. darn that stuff. arghh.
don't really know what else to say besides say it seems to me you are doing the best you can. and even then, i too know how it is to feel like one is slowly going nuts, or being a smidgeon from nuts.
docs tell me that the people who are "REALLY" nuts are those who are completely convinced that they are completely sane, and it is our own very doubts about losing sanity that keep us on the sane side. if that is at all reassuring.
how is Trip's sore? has it healed up? any changes?
sending many hugs.
