Unfortunately the NHS in my experience are a waste of space regarding mental health. I have received more valid mental health Support from charity’s than what I have ever been offered by NHS.The only thing anyone can say for sure is that you need to be in a very dark place to take your own life. That’s it. That’s all anyone knows for definite. It’s very sad. Why it happened only Caroline knows. The best thing for people to do now instead of speculating why it happened is keep suicide awareness at the forefront of the conversation along with discussion about access to mental health services both NHS and privately.
