Has anyone ever felt so alone even with having tons of people around you? What is the point of living?

Lately I have been feeling very alone. I feel as though the world is turning, we are getting no where, i am getting no where. My life is pointless, love is a silly excuse to find a point to life, same goes for happiness. In the end it seems as if everything in life leads to one thing: pointlessness. We attempt to find a reason to move on, to live life, to do work, to marry, to love, to whatever. It just seems like with everyone around me, I am still alone. Alone forever I stand, watching the sky turn from blue to black every day, every night, pondering upon the same thing, learning that in the end, my life is for no reason. I'm sorry if I sound really depressing. its just that I can't concentrate on my school work or my work for internship. I seem to just feel this emptiness that consumes me. I feel that loving is pointless because it ends in pain one day or another. Feeling is stupid for the same reason. And as for working hard, it may/may not pay off, and even if it pays off, its only temporary. Everything is so temporary, what makes it worth it? What motivates you? Idk...I just feel so lonely. Anyone feel like talking about the grander things in life that somehow some of us are granted the ability to just ignore..[geez. I wish I were someone who could pretend these bigger questions were answered by "God" or something or the other] Anyways, thanks for reading to those that did..If anyone want to talk..I would more than love to.
