I too identified myself by "who" I was...a wife, mom, teacher of my children...my family was my world...my H was my rock...
The problem with this is just because we want to be a mom and a wife doesn't negate that we are an "individual"....when we lose that inside of a R...inside of our family and feel we don't have any indentity now that we are not a wife...or may not be a wife anymore...that we might have to go to work...that things in our world have changed and now we don't know who we are???
You need to go back...before kids...before H...discover what it was that you enjoyed...reestablish yourself...keep some independance...I have done this...I won't ever identify myself first as H's wife...if anything were to ever happen to him I need to know that "I" am going to be okay...I have myself...I am strong...and I have dreams and goals that are my own...
