My family is well aware of it. They have accepted the idea and I'm content with it, its so sad for me when someone commits cbt and doesn't inform or give any hint about what they are going through, i know there are circumstances where you cant tho. But back to your question, the first time i commented on the topic they weren't surprise at all, ive been suicidal since i was in highschool and when i finally came to the conclusion that life doesnt worth living. I drove up to my sister and opened up about how i was feeling recently, she was sad but rapidly embraced the idea. She told me sth like we cant force anyone to live a life they didnt choose to have, she would definitely would be sad if im gone, but the decision its up to my. My mother was way more difficult to convince, she's the type of person that likes to quote nonsensical thrashy posts of Facebook, like youll get by, such is life, everything is going to play on your favor one day it never does. As time went by she became more and more open-minded about the fact that i will kill mysef, i explained to her the joy that would be for me when im finally finishing me off. That i just afraid to suffer more, that im afraid of losing them as they are my only family (mother and sis). She understood and wished me the best luck and told me. I will miss you until the day i draw my last breath, but at least when i get a call telling me that you're gone I'll know that your yearning wish has come true and that was your willingness.
