I'm not one for fluffy BS, but the way I see it there is no point in suicide. You're going to die someday anyways, so f**k it. The only difference between now and later is that between now and later you can have moments of enjoyment.
I'd say, find one thing or topic that really interests you, and just learn everything you can about it. Then write a book or blog about it. You can expand the pan-human consciousness of something and be a part of something larger than yourself.
