Certainly Identifying Uncertainty

It used to be that I would get overwhelmed with a sense of uncertainty in who I was.  I was uncomfortable in my own skin and around others.  I seemed to doubt much of what I would say and how presented.  Unfortunately and maybe a little fortunately, these doubts seemed to have come after particular situations in which I believed I asserted myself only to have someone feel the need to critique my words, my cooking, my decisions, my mannerisms, etc. in these situations. 

I once heard an author state that we "need to be grounded in who we are, or we are in a constant state of flux."  She went on to remind that we are not the labels others put on us or name call us.  After listening to her, I realized that my entire life I've accepted, put on, and lived out all of the labels and names put on me by others; some positive, but sadly mostly negative.  I've often credited therapy and my co-dependent course completion as tools in my confidence building success; however, I seem to have forgotten that sometimes even though it's an addiction to negative behaviors and not a physical substance we (co-dependents) can relapse as well.   

Could this have just been a relapse?  Was it as simple as reviewing my co-dependent information, and diving into my faith, and "working the steps?"  Or am I doomed in my life's journey to have to continuously struggle with believing in myself, building my confidence, and not apologizing for who I am, what I say, or what decisions I make? I guess only time will tell.
