An acquaintance, she was 18, closer to my sister. It's possible that some of my old online friends have succeeded in their attempts, I wonder about some people I haven't talked to in years. Many of my friends (past and present) have tried and failed. I have too, and quite frankly I suspect it runs in the family along with depression but I haven't asked.
Sorry for slightly off-topic, just needed to vent this... I was personally more messed up about somebody I knew that got murdered at a young age by another acquaintance of mine. I can understand suicide, and I think it's your choice to kill yourself for better or for worse and if you've really thought it over then whatever I'm not your boss, but I can't forgive murder.
