I am not sure what changed and I became this way. I didn't work towards it or strive for it, I just grew older I guess. So I came up with a theory. Not even a theory, more like an opinion...
That when we are younger we rely on society to survive. Without a support cycle, the elements will overtake us, and our animalistic instincts light up. Our identity is tied to our social circle. But as we get more confident and more comfortable with who we are, that deep fear of loneliness decreases. I am more alone now but less lonely.
