For me my death is the only way for me to find peace. I will be free from my suffering and I will never have to experience anything again. I believe I will return to the same nothingness where I was at before I was born. I will avoid old age and getting more health problems. No more pointless existence and I will not have to be me anymore.
For me the things that hold me back, and are cons are the survival instinct as us humans are programmed to survive and the fact that methods can go wrong and require planning. Personally I want to disappear and not experience the dying process. Of course others will be sad, but when I am gone from this world, I will not be able to see their reactions so that is not a concern to me. I would rather not cause others pain though so therefore this can be seen as a con, which is why I said I wanted to completely disappear.
