Dying is something that will happen to all of us eventually. There's no point in rushing it, and TO "rush it" is too scary anyway! It's very hard to off one's self! Very terrifying. Much easier to just accept that life may not be as grand as we'd hoped, but it does have its comforting rhythm (even an awful life, people get used to what they experience as 'normal', and even depend on it - so a person living in seeming tragedy will defend getting to still live that life! And it's just an instinct to survive that we have, plus an ability to adapt. And this is what gets people through.
But when one gets depressed enough to contemplate continuing to live, then is when it might help to take some examples from people who've had to live with depression on and off all their lives. There are ways of snapping ones self out of it. There are ways of bearing through a low period, knowing that a good period will follow. And this is the advice I would give to you, the answer to your question (which I took as "what makes living worth sticking around for?"): there will always be some happy moments here and there. And they are what makes it worthwhile. You're going to die one day anyway, so what's the hurry, stick around for those occasional happy moments. Look for them even! You know..break into song, tell a joke, share a loving moment, create something.. the little things. It's about little things. Little moments of content.
And I'd recommend a visit to a book store, to the self help/ spirituality & psychology section, where you will find wonderful books that sell the value of a few happy moments along the way so compellingly.
You'll find books there too that, without being in any way about god belief, talk of living spiritually - books that report on the things we know about intuition and being connected and having inner wisdom to rely on and such, that can make you feel very powerful as the creator of your own life. Wayne Dyer has published dozens of these books, and gives wonderful inspiring speeches on PBS at pledge times (and you can find videos of those speeches on you tube, for free
Me, I very much liked The Celestine Prophecy, which a friend gave me, to get me started. Again, it had nothing to do with god belief, just observations about intuitive powers and being connected that we all have. Potent stuff. Changed my life.
So go on a quest, LunaClare! It will be something to do that could interest you. And being interested in something makes life seem important, even worth while.
(And don't be afraid of seeing as doctor, if the depression doesn't lift. One in four people has had to get a little medicinal help with snapping out of a period of funk. No big deal. (HOWEVER (CAUTION): Pills do create side effects though, and I would recommend FIRST try a natural remedy, like the following:
1- walk daily
2- watch or read something that will make you laugh, DAILY
3 - find something to be interested in, a project, a reason.
4 - if you don't have someone with you, for gods sake get a cat.
I've been alive YEARS longer than I would have, because I wont abandon my little friend who depends on me. He makes me have to get up, he makes me unable to just string myself from the ceiling. And most of all, he lets me feel some happiness, each day, when I wouldn't have. (When he cuddles on the couch with you and lets you know there's nowhere else he'd rather be than watching the telebision with you in the evening, all the cat box cleaning and ripped curtains pay off then. Trust me. It's nice. Love, even for a treasured pet, is wonderful feeling. And you should feel it daily, and have someone to fight for.
This is my friend and constant companion, Captain Meow:
I keep him entertained ~ and he keeps me from visiting Dr Kavorkian's self-help page...
This is him
No, wait, this:
I wish you a little moment of happiness each day.
That's plenty better than nothingness!
