Puzzlingly Puzzled Puzzle

I so much feared to face, but I knew you would come.
I wasn't waiting for you at all.
You knew I wasn't welcoming you, but you came anyways.

I thought I couldn't deal with you.
I was too nervous, stressed, even sick.
However, when I saw you nothing big happened.
I found out I am pretty much indifferent with your presence.
I guess you are much less important than I think.

I don't know how long you would stay,
but I am not frightened anymore.

So, I guess I won this time.
