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
'Cause I had to say goodbye
By now I should know
That in time things
Would 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

'Cause 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 realise
Your actions speak much
Louder than words
So tell me why, oh

By now I should know that
That in time things
Would 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 you behind
So why do I feel so sad
If it couldn't be that bad
Tell me why

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