i am so very sorry for your loss. 'it could have been avoided' are heartbreaking words. i have heard of and experienced many instances where the medical profession made errors which resulted in death. medical staff are busy and stressed and mistakes can be made or clear communication can be lacking. and when you are grieving you don't have the energy and mindset to look for proof of the errors and to fight for accountability. it is infuriating. i wish i had more comforting words. just know i can empathize with what you and your dad are going through and wish wish wish your mom was still with you both.
