First off, my sincerest condolences to the parents, friends, and family members of the person involved. I cannot imagine what they are going through as a parent.
Also, I'd like to point out to people who may be questioning how the parents didn't catch on to something being wrong with their child - many times there are no signs,, or if there are the signs are very subtle.
When I was a junior in high school, there was a boy in my history class that committed suicide. Hos mom was an English teacher at the school and he had called the guy that sat behind him that night to ask what chapters were on the test. The next morning, his mom went to wake him up and he didn't get up. She went back in the room 10 minutes later when he still wasn't up and saw he had taken his own life. We heard there was a note, but we never heard what was in it. Obviously, his mom never knew anything was bothering him to the point that he would take his own life. We never had any idea about that either.
There is a show on Netflilx called "13 Reasons Why" about a girl who ends up taking her own life. In season 2, it points out that the parents had no idea that anything was bothering their daughter. Believe it or not, this is the case for most cases like this.
Lastly, I'd like to point out that while some people say that someone taking their own life is "greedy" or something similar, nothing could be further from the truth in the person's mind who did it. Most of the time, these people think they are going to relieve their close ones from having to take care of them/be around them/etc. and think of themselves as nothing but a burden to those around them. Please don't diminish that by saying it's "selfish" because it certainly isn't. When that is the case, it isn't selfish, but there is a huge misunderstanding about where that person falls into other people's priorities.
Again, my condolences to the person's family and friends.
