I am so sorry you are struggling. You have had trauma after trauma. Your body has gone through a lot. You have gone though a lot. I recognize some of the same losses in my cancer journey. Loss of normalcy, loss of who I was, loss of who I thought I was going to be and how life would be. Loss of my self confidence and self suffecincy. But your reactions are a normal response to all these challenges. I experienced periods of low motivation and I guess loss of hope.
I believe you can find your way thru this. You've come so far already and survived such hard times.
You have a lot of good suggestions for you already, and I echo them, find someone to talk honestly with, get out in nature even if it's only to sit in the sun.
Do something you enjoy... create something... something new. Paint, write use you creative parts. Journal if it helps... I did one word journals ... just one word to describe how I felt at that moment . It helped me process and took little energy .
You'll have to be brave some more... just to make yourself do these... but you've got this!
Prayers for you !
