Personally, I've been keeping journals and typing notes on my phone for the past month or so. I just want my general thought processes to be understood really. I do go in some of my writing how if I had actually been raised and hadn't been emotionally neglected and then manipulated by my parents then I probably wouldn't be in this situation.
I think it's mainly up to you, but I'm not too worried about hurting feelings after I'm dead. I've been made to feel like I've fucked up just about everything I've touched since day 1 and I don't really care if this fucks up the people that should've known better than to treat me like that anyway. I mean for fucks sake how hard is it to just love your child anyway? Whatever.
Point is you can do what you want, but I've been broken to the point where I really don't care what they think after I'm dead. It's not like my last words are going to be changing lives or anything like that. You may feel differently though. Just trust your gut here really.
I hope you find peace, whatever it means for you soon, friend.
