Identity

So, in my haze of self-realization and honesty I have discovered that I know absolutely nothing. I know, shocking. Trying to find and maintain identity with this realization is a bit of a struggle, and at this point I am feeling simply frustration. In trying to answer fundamental questions about myself (things like: who am I really? What is it that I want? or even simply What am I going to major in?!) I have realized that to different people I am different things. Is this part of being an adult? compartmentalizing who you are? I certainly hope not. However, I find myself being different people at different times. Revealing only what I deem to be appropriate for the situation, and then hiding the rest. Sometimes, I care far too much about what other will think of me, and this needs to stop.
It is in this vein of thought that I feel I should at least mention the reason for my temporary insanity. Being 25 and going through a separation is not something that I necessarily wish to broadcast, but feel that for my own selfish purposes it's a fact I should put out there. I am now living with a roommate, instead of a spouse. I am trying to readjust my whole life, and find out who I am individually because that is not something I did very well while married.
Perhaps this is what would be deemed a quarter life crisis, although I'm not really a fan of that term. I think that people should be allowed, and encouraged, to continually evolve. To find out who and what they really are. If and when that changes, it is the beauty in life that allows us to adapt and grow with each flexing moment.
