Isolation - the process or fact of isolating or being isolated: isolation from family and friends may also contribute to anxiety.

What I used to think: I can't imagine a world without my family and friends.

What I think now: I don't remember what it's like to have a family and friends.

I once had a mother. I once had a father. I once had brothers and sisters. I once had friends. They are all dead and gone. Old age took them. I am alone.

I hate the world. Life is cruel. I wish I could just curl up and die. But I cannot. I am immortal.

As long as my heart beats, I shall live. Forever and ever, until the end of time. Everyone I ever knew and loved is gone. I am used to loneliness now, but some mornings, when I awaken, the realisation that I have no-one left cuts me like a knife.
