I am so glad you found a parh to healing from the death if your Mom.
Similar stories are playing out every moment of every day here in the US.
Unless and until “lawmakers" start writing the laws instead of delegating that task to special interest groups, like insurance companies, and a host of other profit driven, greedy, heartless, spineless business people, people like your Mom will continue to die from preventable diseases.
The best we can do is offer support for each other, reminding ourselves that we are all going to die at some point. This is the fact for all living things.
May your remaining journey through life be tempered by knowledge that you did the best you could for your Mom and your family, then and now.
