Yes... but I have already told them that this will happen with a great deal of certainty. It took them around 2 years to "accept", and by that I mean that they know but won't try to stop me. I had came out to my parents as gay 6 years ago and while there are many important differences between that and telling your parents that you are choosing to die, I see that there was a similarity in how their ideas changed very slowly (and the first months were, oh boy, very messy and emotionally violent) and how they eventually came around to at least try to understand me. My parents are deeply religious and I knew this would mess a lot with our family, and still does in a smaller scale, but I chose not to hide any of this from them. And now I'm glad I didn't. I know they will be devasted when I go, but honestly, if they love me, they should let me go and respect my choice. I have been living in hell for 6 years now, every single day, (and not because of any of this) and I have come around the notion that this is what I truly want for me. I still a little doubtful, but it's very likely that I will CBT this year.
As my friends go, they all know, they all care (not as deeply as my family probably, but I know they still care) but all of them have a very progressive mindset so they are all ok with me choosing to die.
