I think the problem is...we never really have the full picture. We make responses on the information we are given, and people are always going to disagree.
On the face of it, from the first post, it does appear to be emotional blackmailing. However, I tried to see it from a different perspective.
Once the OP posted a bit more, I felt a slightly different picture emerging. I’ve no doubt she is in pain, and very unwell mentally. However, she painted a different picture of her ‘past self’, when she talked about the 2,000 people who worked for her. That’s a strong, well adjusted woman, who is quite clearly able to think for herself, and take charge of others.
Is it that she’s been a difficult person in her home life, and this is the basis for the SIL’s behaviour, and her own daughter basically condoning it?
I’m not saying any of this is how it was. It’s supposition, but in my experience, people rarely turn their backs on kind, loving people.
I agree, the daughter should not be involved. It’s between the OP and her doctors.
I wish you well Lollipoplove
