Hello??? Whose may I ask is calling??

As I read through many of the blogs that I follow, I'm continually struck by how wonderfully unique and how clearly the person's personality comes through. I bring this up because I often question what my authentic voice is...am I being true to it...is it coming across as clearly as I would like? I know I'm not the cute, perky...so lucky to be -in-love-and-life kinda person...nor am I the serious dedicated writer or the witty, smart-mouthed hipster....so where oh where in this bloggy world of ours( and admittedly in the real world too) does that leave me?? It's so hard for me to find some type of semblance and say with surety that, " hey, this is me!" My interests can change as quickly as the breeze and something that I may be passionate about one minute, will be yesterday's news ,in the next. I swear sometimes that the only constant I've got in my life is the threat of sliding down into a depression that I can't drag myself out of.:( So ,I guess what I'm asking is how do I come across to you dear friends? I don't ask from any place in need of an ego trip...just wanting to try to bring some light of understanding to the dark caves of my ignorance. Maybe that really is a question better left unasked...but you know the old saying...A life left unexamined isn't worth living(or something along those lines....)
