who am I ?

sometimes I wonder if I am me or if I'm the version of me only other people want to see. I don't know who I am when I'm alone. I'm a deferent person for everyone I meet I know I have over one thousand personalitys but I like me best when I'm with you I'm kind and caring and I know that I can be true to myself when Im with you so many personalitys and yet I like myself the most when Im with you that says Alot
