What keeps you going?

I'm finding it difficult to feel anything rewarding about life, there's no incentive to move forward and achieve something because i have no one to share it with. The future looks so bleak and bland, i'm not going to have a wife to love, kids to nurture, friends to have fun with, what's the point really? You can say "well just get some hobbies" but how long will hobbies distract you? Especially when we live in a society that feels the need to shove romance, love, sex and socialisation in your face.

I'm just running off the evolutionary programmed need to survive and fear of death, otherwise i would've killed myself long ago.
