One of my best friends committed suicide back about six years (!) ago.
Now, I don’t lose my shit in public. When I found out about it, I was in Bed, Bath and Beyond. My mom called me on my then-husband’s cell phone–mine was never on–and told me what had happened. I was 21, and I broke down, crouched on the floor, crying. I had to be guided out. The immediate impact of that grief was massive. It hurt.
The day before I found out–the day that he died–I had lunch with my mom. She asked about him. I said we hadn’t talked in a while. I went and gamed with another group of friends, with the idea that I should give him a call soon. See what was up. I think I’ll always feel guilty that I didn’t right that moment. I’ll probably always think that, on some level, I’m culpable for his death.
I would not wish either of those things unto my worst enemy. I would not want to go through that again. I have friends who are depressed, and my biggest, most selfish fear is that they might decide to end their own lives. I’m not strong, and I count very few as friends. That would break me.
So, yes, I think that suicide is, in general, even absent of religious belief or other obligations, unethical. Surely there are exceptions–for instance, those who are mortally physically ill and in excessive pain–but, in general, I think it’s deeply unethical. It can destroy others.
