Again, unfortunately yes. I knew two people who committed suicide and my mother has attempted suicide before.
A family friend was accused of something of which there was no proof except one person's word against his and after struggling with depression for a long time he tragically committed suicide leaving behind two sons and a wife, all of whom are extremely nice people. As his brother said at his funeral it the accusation and rumours it caused was akin to opening a pillow full of feathers on a mountain top and trying to gather them back up again.
After my parents divorced my mother had a nervous breakdown, was extremely depressed and tried to take her life on more than one occasion. She was admitted to a mental hospital twice and was treated with ECT and very strong anti-depressants and subsequently has no recollection of around 6 months of her life. Coming back from Uni to find burnt ends of hosepipe and pillows in the garage, labels with people's names stuck to paintings and items of furniture is not something that I ever want to have to encounter again. The last time she tried, she overdosed on paracetamol and left a garbled message on a friends answering machine which triggered a call to the police to go to my house and who made the call to the emergency services and my mum's life was saved.
In the months and years that have followed many times I have thought that it may have been better for her if she had managed to take her own life. She was in such a dark place and subsequently made it very, very difficult for a lot of people but more so myself, my sister and her father. Some people may be surprised or horrified that I would say such a thing but at the time it was what I truely believed.
During the last 2-3 years there has been a huge improvement in my mother's mental health and most of this can be attributed to the birth of her first grandchild. My opinion above never enters my mind now as she is so much better. We are all still very aware of her fragile mental state but hope that she keeps getting better and better with less and less relapses of poor health.
