People should be free to decide if to exit life under their own terms.

If I look at my mind, then I can say I've been depressed mostly because I haven't known who my true mother is/was. And since I tried to project on my biological mother and the world, qualities of my true mother which were too high for them, I found myself in a captivity of sorts. Slavery, drudgery, the list of de-motivators is high. There's another aspect; this time, about the entity I call 'me'. I set some standards for myself, but I'm too weak to be able to live the thought. Only training can help... Oh, imagine the dynamics of training. Which training is this? Where's the trainer? You don't find one as easily. 'I'm a failure' you say. Let's call it the institutionalization of Babylon, in my mind. The deepest aspect of 'the depression' is my alienation from the unconscious. I believe that if an individual can be receptive to the unconscious, then he/she has everything he/she needs. Knowing who your true mother and father are is the sweetest thing ever. Your days are full of joy, life is eternal! In the end depression is a good thing and should be encouraged. If one is depressed, then that person is ready for enlightenment. Just don't give up! Suicide appears as a way out some times. But in a knowable universe you discover that death is an illusion and killing yourself is self deception. An individual's mind can't be trusted! You need to control your mind, but not the other way round.

Why "selfish"?

Coz of those you leave behind spouse, parents, kids, siblings, friends People are left blaming themselves

Exactly. You live with guilt for the rest of your life asking you whether you could have done it different. Was your approach wrong? Was there a way to stop it? Where were you when it happened? Why didn't you sense it?Why,why why is what you will take to your grave. It's done.It's over.And you have to live with that forever.
