Excellent question.
My answer may disturb some of you so be aware that it could worsen your state of mind if you follow reading.
If you have a caring family, close friends, etc... I won't lie, it will be terrible for them, there is no doubt about it. People around you could feel anger, guilt, frustration, betrayal... they may feel ten times the pain you're going through yourself. This is extremly sad.
Even with time going on, the pain will be part of their life. It is devastating and unpredictable. This is the main reason I'm not being impulsif right now. I have to find a way to reduce the pain for my family.
Today I wrote a letter, it wasn't part of my plan, now I'm trying to look for testimonial of people having a loss (especially from parents and siblings ). Each time I try to guess what my parents would feel, I end up crying. On the opposite I don't give shit about my own death. My aunt passed away few month ago from cancer, I didn't feel anything, while my dad (his brother) was really sad. I guess it mainly depends on how you can relate to people, what relations you have had with them, what reason bring them to die and how they did, if they suffered, the way you hear their death, and so many others things you can't control. I know it's not pleasant to hear this but I would rather chose to know this in order to try minimizing the family or friends circle pain.
Besides some of us may have altered emotions, in my case because of schizophrenia, I have unaproprial or lack of emotions. I know this is not a "normal" brain reaction.
I wrote bad english hope it won't be misunderstood.
