Did I know you?

I don't know how I feel,
What to do,
Or even what to say,
The fact that I can't tell you,
You're not there to listen,
Or give any advice,
Seems like yesterday,
Sometimes just a nightmare,
Or do I call it a dream,
Can't call you on the phone,
Not write you a letter in the post,
Or see you face to face,
Do I feel angry,
Maybe happy for you,
Or just sad you left,
I didn't get a choice,
Is it because I wasn't there?
Or did I just not understand?
I'm doing okay,
Shall I be here in this time,
Or should I be with you?
What ever happened,
I do not know,
Or am I being blind?
I didn't think this,
It just couldn't be true,
Or I just never knew you....
