I've known three people who committed suicide. The first I didn't know very well, had never talked to him in fact. My best friend in high school, Amber, was friends with him. She felt responsible afterwards because she had been talking on the phone with him just a few moments prior to his suicide. She felt she should have been able to see it coming and stop it. He killed himself because he had gotten a girl pregnant and didn't feel he could support the woman and their child, and his twin had recently died in a car accident. He never recovered from the loss of his twin. Amber never recovered from the loss of the suicider, she took far too much responsibility for all her friends after that.
I didn't know the second one very well either. He was a couple years behind me in high school. He had a steady girlfriend for several years, straight A's, and a family who loved him dearly. He and his girlfriend got in a fight one night and she broke up with him. He got drunk and shot himself with his dad's gun over the loss of the girl.
The third I knew very well. I worked with him closely for about a year. He was one of my supervisors, and we worked in a small area together daily. He was molesting the 5 daughters of one of our other coworkers as well as the daughter of our boss. When he was found out, he hung himself rather than go to jail and be subjected to the justice the other inmates would have given him. I was sad at the first two suicides. They were young and their deaths were tragic and could have been prevented. The third suicide made me very angry. He knew what he was doing was very wrong. He completely destroyed the childhood and innocence of 6 very sweet little girls, all of whom I knew and meant something to me. He was too irresponsible to handle the consequences of his actions, so he took the coward's way out. I always wished he would have gone to prison and gotten what he deserved. It's harsh of me, but I can't be nice all the time and certainly not to child molesters.
