My aunt had a very long history of mental illness & finally she could take things no more & age 50 she killed herself.
About 10 years ago a work colleague & friend couldn't cope with the break up of a relationship on top of other issues he had from things he saw in the army in Northern Ireland. He had one attempt but stepping out in front of a motorbike was unsuccessful, sadly the second attempt using a car, hose pipe & bottle on Vodka was 🙁
Both left family & friends asking questions about why they did it & could they have done something to help/prevent it.
My best mate attempted it once but it was more like a cry for help & was a hard lesson learned. We have always kept in touch & even now he's 12,000 miles away we are there for each other if needed.
