Invisible

I know, it is crazy but I cannot help but feel invisible a lot of the time. I e-mail volumes and hear nothing. I post on Facebook. No response. I blog to silence. I write letters, ask questions, initiate communication, talk. My words seem to evaporate in the air. Am I hidden? Has everyone blocked me? Have I been cut off? Am I really that dull, unimportant, invisible? (Is everyone so self absorbed?) I am sure a lot of it is something I carry with me from a turbulent past; those pre-existing, deep seeded doubts and insecurities. They must ooze from my pores and surround me in an invisibility cloak, my very own self-fulfilling prophecy. The question is, how do I undo it?
