I Have Finally Learned

I have finally learned to say
Goodbye to the one I love
To the one that was there
When my skies were grey

I have finally learned to say
Goodbye to my best friend
To the one who always said
I'll be there to the end

I have finally learned to say
Goodbye to my only sister
To the one who I loved
Even when you were bitter

Better days are coming
For me and for you
So you have got to learn
To say your goodbyes too

Please comment on my poems, I would really like to know how I am doing.
