Do you know me?

I think we may have met,
do you actually know me?
How many times have I changed, and not changed back?
Did you know me then, too?
Seems I'm an enigma to my friends,
So they don't know me too well.
they want to,
I want them to,
but they can't seem to figure me out yet.
I can't help, I'm in the dark like you.
But when they asked, I would say;
I do know me.
I know who I am.
So, do you?
I know I change a lot,
And thats bring us back to my question...
I guess you're going to have to try
to get to know me,
Aren't you?
If you're not up for it,
Then you're not worth it, are you?
So,
Do you know me?
I wish you did
