Is this song a good way to say goodbye to someone who I thought was my friend?

I thought this person was my friend. But apparently its not true. This
person denies it but I can see it in his eyes. So this is my way of
saying goodbye by sending this song for helping me temporarily with
depression. But final goodbye because I keep getting ignored and
everything.
