You know, I have one suggestion for everyone contemplating suicide.

Hold off on it until you die some other way. Worst case scenario, you lose nothing and are just delayed a little bit on your way off to who knows what's beyond. No big deal, eh? Just have to be patient - You can't tell me you're hurrying to the afterlife, when the human lifespan is no doubt a drop in the bucket compared to whatever afterlife there may be.
On the other hand, things could take a drastic turn for the better - And hey, after that, you also get to go to wherever you were planning to go. Two for the price of one!

Conversely, kick it up a notch and search for a meaning in life in doing something significant. Sign up with the Peace Corps and go help disaster zones across the world, Volunteer for your local Volunteer Fire and EMT services - Anything that'll give you something positive and significant to do, where you can immediately see what good your efforts are doing, even if you lose whatever you're working on (Which doesn't seem to matter too much to you as it stands if you're contemplating suicide)
Again, worst case scenario, nothing lost - You just end up going wherever you were going to go by commiting suicide anyway. Hey, you might even be hailed as a hero if you're killed in the line of duty while saving others, and on the other hand, you could have just found something that'll lead to a life of significance and happiness for you.
