It's a prefix meaning "not", freely used as an English formative, giving negative or opposite force in adjectives.
I'm not looking for comments in this post. I just wanted to use this as an outlet for my crappy feelings of late. They say, if you write things down, it's easier to let go of them...whatever they are. I'll let you know how it works out.
I have never felt so un-appreciated, un-attractive, un-loved, un-acceptable, un-cared about or un-cared for in my life...
And what is really making me nuts is, as Eleanor Roosevelt so adequately put it, "no one can make you feel inferior without your consent."
Which translates to...I'm allowing this to happen.
Get a grip, Joyce!
