People seem to think that when you're on the verge of suicide because of depression (what appears to have been JewWario's case), all you're thinking about is yourself. And in fact it is, but not in a selfish "it's all about meee!! Give me attention, give me things, love me!" manner.
Selfishness is something reserved for those thinking rationally. Depression disables rationality. It muddles your perception of reality, and twists it in a manner as to make you feel so worthless that your presence is not making a shred of difference on the world, all while making you think that it'd be better if you disappeared (if you ceased existing, all the disconfort you cause others with your problems, and your own pain will cease existing too, right?). It's a feeling of unimportance on an unbearable scale. And it's not like those "If I go sleep, this bad feeling will be gone". The person afflicted stops accounting for the future. They want an answer right now.
It's not about yourself. It's about your importance to the whole that is humanity. Sure, you can be told every fucking day how you're important on the lives of those around you, but that's not how a depressive brain works. You know you are important, but you don't feel important. You feel nothing at all; It's just like having an infinite void eating all your energy and thoughs every damn day, until it has consumed your whole being. Everything just stops being important, as you feel more and more insignificant.
The brain is damaged, the mind becomes warped when you're depressed. You cannot be selfish, because you cannot be anything but terrorized with your own insignificance.
When you decide for suicide, it's almost like you are finally deciding over something. You feel like you finally have the power to change everything. You feel as if the control, amidst all this darkness controlling your mind, has finally been given back to you. You can end it once and for all. But you're unable to recognize anything else. You're unable to recognize the impact this will have on the life of others. You cannot be selfish when you don't even have a sense of "self" anymore. You're not intentionally making it all about yourself. All you seek is to reclaim normality, and make it all stop. You stop recognizing the world around you because you feel like an insignificant atom; Unseen by all, unable to change anything about it.
Of course all this is unnatural and wicked. Depression is all about your head not working properly and leading you to reckless actions.
I tried to explain to the best I could how it feels. When you cease feeling important, you cease seeing importance. And depression is making you feel uninportant all the time. It's nigh impossible to fight irrationality rationally. All you want is to stop feeling uninportant. Stop feeling anything at all. I know it's confusing and seems contradictory, but that's what went through my mind when I felt like this before. I dunno, maybe it's different for others. But I feel personally hurt when someone says the person is only being selfish, for selfishness' sake, even though I know it was not for me.
When you watch the person onscreen, you have this feeling that they are immortal, with no problems, and will always be there. But when these things happen, reality comes crashing down again. I hope Justin's family can do well without him. My condolences for his family and friends.
