My mom dealt with cancer at the end. She went through several surgeries and courses of chemotherapy that were horrible to endure.
When she lost another short remission, she told me she didn’t have it in her to endure more chemo, if it was ok with me. I explained that in her shoes I’d have thrown in the towel years ago with the initial diagnosis.
Then she talked to my brother, who gave her the @Smapti hard line suicide is wrong, you may still win this battle lecture.
She suffered through another few months of absolute misery. I’ve never spoken to my brother about this.
