Best of luck with everything. That's a lot to take on and I can understand being burnt out. I lived with/took care of my grandfather for about a year and was very ready for help and ready to move on after about a year. It broke my heart to move out, but I NEEDED it, for ME. Not the same situation, but similar and I at least kinda understand what you're going through.
Anyway, I admire your courage to stand on your own two feet and make a pretty big life change. You're in my thoughts and I'm sending my best wishes your way. Good luck! You got this!!!!
