Listen up. I haven't been diagnosed officially, but whatever, I strongly suspect having BPD. I dont even think it's that bad of a thing (right now) but that being said, I and I presume you have struggles in coming to terms with self, and what is self. 

For me, the self is not a concrete identity, although I know I'm me, per se.; I dont know what I want to do and how to come to terms with some sort of inner peace. If that even exists. Does this sound familiar? how do you internalize yourself?
