Why Do I Feel so Sad

Friends we've been for so long
Now true colors are showing
Makes me wanna cry, oh yes, it does
'Cuz I had to say goodbye

By now I should know
That in time things must change
So it shouldn't be so bad
So why do I feel so sad?

How can I adjust
To the way that things are going?
It's killing me slowly
Oh, I just want it to be how it used to be

And I wish that I could stay
But in time things must change
So it shouldn't be so bad
So why do I feel so sad?

You cannot hide the way you feel inside, I realize
Your actions speak much louder than words
So tell me why, oh

By now I should know that
That in time things must change
So it shouldn't be, it shouldn't be so bad
So why do I feel so sad?

By now I should know
That in time things must change
So it shouldn't be so bad
So why do I feel so sad?

By now, by now I should know
That in time things must grow
And I had to leave to you behind
So why do I feel so sad?

If it couldnt be that bad
Tell me why?

By now I should know
That in time things must change
So it shouldn't be so bad
So why do I feel so sad?

Oh, why do I feel so sad? (why do I feel so sad?)
When I know that it must change (why do I feel so sad?)
It must change, I don't mind
Just be real with me, just be truthful
And the rest, I'm leaving up to this one, yeah
Why does it feel so bad inside?
When I realize that you got to be left behind? (I feel so sad)
