I am a stranger amidst known faces

Why this feeling of stranger still exist in me?
All known faces to me, some of them I know from the time of I came to this world, some I know few years later.
I have talked with them a lot! some have talked back to me some have communicated through their silence. I can't even say there was communication gap because I was loud enough may be I was not clear enough in communicating with them. People who communicate with silence are the most unknown minds... They scare me!
I loved them, I took care of them, in return they have started clinging on me.... May be I was not clear in drawing a line between caring and caring beyond the limit. May be I need to learn the difference... Will I?

Are they strangers to me or am I stranger to myself who has neglected to know myself but busy in understanding others which was not necessary. Was it not important to give importance to myself before giving attention to others?
So many questions but yet to find the answers, will I ever seriously try to find answer... don't know!
Yet life of a confused stranger is going on amidst known faces but unknown minds and some unknown faces but known mind.
Life of a stranger in indeed strange!
