the glass wall

Strange how I can go through most of my days and feel fine about who I am, what I'm doing, where I'm going and what I have; then, as if someone threw a wall in my face, I am hit with a sense of profound loneliness. I typically spend my days and nights on my own, with few people to call friends and even fewer to spend any time with; I am quite comfortable with being on my own. Until, that is, that wall falls directly in my path. And it feels like a wall too, a giant glass wall slamming down and trapping me, alone, however transparent to show me that the rest of the world exists, and quite happily, without me in it. Showing me that I am quite alone and reminding me that I am not always happy with it. 

Cheers.
