I actually started writing notes, the most detailed one for my best friend, two more for friends that have always cared and one for family friends. Only the latter has been completed because of less emotions involved.
The final would be for my parents but I haven't even started writing yet, I get too emotional and cry too much.
Anyway, I would try to explain what drove me to my decision, I would stress out that nothing they could have done would have helped me, that my parents did nothing wrong in raising me, that I love them immensely, that I had an intense and fulfilling life but now have reached a point where I feel broken beyond repair.
I would then ask to be cremated and my ashes be scattered, NO funeral service, and finally would state what I want to be done with my belongings.
It would be very hard for me since I know that nobody would truly understand the reasons why. Plus, I have people who care (albeit only a handful) and loving parents, something most of you don't have, and that makes me feel guilty.
But it's not the time yet.
