Bluemountains, this is awful. My then h also shared the information about my suicide attempt with my dad, cousin, and uncle, but he did it when he was at the end of his rope not knowing what to do with me and expecting help from them since they are my blood relatives. No help came along, trust me on that. Instead, my uncle demanded money that he thinks I owe him (delusionally). He is the only one who lives close by and he did not visit me when I was inpatient on a locked unit. He instead continued to bombard my ex with demands for money. My cousin and father had a plan to disinherit me from my late mother's property on the grounds that I am incapacitated (they did not succeed, thanks god). My cousin tried to make me see a p-doc who is her friend because she wanted access to my medical records for that.

I know that what I wrote is only tangentially, and even that at best, related to your pain, but I wanted to share that relatives can be fully and totally unsupportive.
