I'm Alone and I'm Scared

I am one man against the world it seems. Friends have abandoned me, love has abandoned me. And slowly but surely all else I had is slipping between my fingers. Besides here, I have cut myself from social media and burning bridges. I've grown tired grasping at what I've lost only to see it all fade away. I cannot rely on people for my happiness, for my sanity. But can one live a fulfilling life void of social interaction? I am a weak individual, starved and craving acknowledgement, respect, loyalty, and most importantly love. I never did learn how to move on and cut ties, I never did learn how to unattach myself from those already long gone.
