Sadly can't say I knew him as well as some of the others here, considering I haven't been visiting IRC lately nor have I been playing doubles a lot, but from what I got from the times I did see him around and from the stories friends of him post in here, it looks like we lost an amazing user and a friend of many and I am sincerely sorry both for Benja, who must have been in a state of total desperation to resort to suicide, and for everyone who was friends with Benja. Please talk to each other about it as much as possible, share how you feel about it on irc, Skype, or wherever, but please don't keep your feelings for yourself, it is essential that you have a place to vent when you're deeply affected by the loss of a great friend. Also, like others have mentioned, if you are depressed yourself, talk about it to people, and if you suspect someone here is struggling with himself, don't hesitate to give that person some extra attention and to ask if something's wrong, make sure that he feels like he belongs and that people sincerely care about him.
Finally, I just want to mention that nobody, absolutely nobody, should feel guilty about this tragedy. I know there are always people who feel like they "could have prevented it" or whatever, but that isn't true. From what I understand, many of you were happy to be around Benja and treated him like a friend, which is all you could have done. No one here could have know how he felt about himself and no one could have singlehandedly pulled him out of it. I cannot stress this enough.
I hope Benja has found peace and that in time, the doubles community, Benja's friends, will recover from this loss.
