Worthless?

Ever been dumped by anyone? Or stopped talking with whom you expected to spend your life with them? I am....many times, some due to my own decisions ,mistakes and some are just plain misunderstanding.
Someone very close to me , decided to remove me from from that person's life..I was totally confused due to this.
Why me? What I done? Showering the person with positive energy is wrong? Support the person no matter what? Care for the person?
All I told became craps....
My expectation that I can make a significant change with the person's life..
Make the person as happy ..but I could not.
I have been removed and rejected many times.
Yet I have been still holding on my base...
Why?
It is my choice to be nice,caring and loving and it is their choice to accept or kick it out.
Losing my base or changing who am I , is insignificant....you can not expect a lion to eat grass nor an eagle to walk on the ground.
What if I am wrong? Is it wrong to be like this?
I do feel worthless after all happened but I can not stop believing because belief is what gets you wake up in the morning. A man without believe is equal to a dead body.
