Bent out of shape... suck it up?

For the longest time I had purposed to hide my thoughts, emotions, actions, etc., from others. It was a proctection mechanism that I instituted to prevent myself from allowing others to crush my spirits (clinical, I know). Over the past five years, I have gradually allowed myself to express more of these things. Over the past year, I have fully let my guard down to a select few individuals - a feat I've never accomplished even with my own family! Since I've open myself up I find that I am, now, truly crushed and bent out of shape when someone sends the littlest of white lies in my direction.

I'm tired of putting up with it. In my head I have already resolved to revert back to my old habit, along with not freely offering trust anymore. I hate the thought, but not more than feeling worthless after the abuse of my trust and having my spirit crushed.

Am I being a sensitive little school girl?
Or should I just suck it up?

In any case, I'm tired of it...
I have yet to pray about it...
And, sadly, I admitt I am not wanting to forgive.
