I feel so empty and blank

It’s to the extent where I’d regret posting something like this on tumblr.  All they see is a meaningless post.  They’d read, and go on.  At the same time, however, I would want to post such a thing because there might possibly be chance where one person would listen to what I say.  And maybe it would hold meaning to both. No barriers, no boundaries.  I just don’t know who would.  And Why?
