I was wondering how this song was I wrote it myself about an old relationship and I wanna perform it for my school talent show... plz let me know how it is and be honest..

In my own head

You made me think bout all
Of this. You help me see
You was toxic all off my
Thoughts yes they played but at least I try
I was so. Blind to see I thought it was
Real I thought was just you and me
I turn around and saw you
Texting my friend and I see
That you played me
Yeah I see all this now
I had lost 4 friends cuz of you
Now I’m all alone where was you
When I was crying
Where was you when my heart broken
Oh right you was the one really cheating
You stop texting now I’m just worry about you
I need sum avidce and I wish I could
Get it but I’m so lost in my head
With a hole in my heart
You said you love me but I guess it was a game
And I don’t want to learn how to play it
Sorry that I wasn't the one
Yeah I guess I had to be the bad one
But thats just not me
Im not gonna change for you
Im not gonna lie for you
Im not gonna sit here and by play by u again
So I’m saying goodbye and I’m saying goodnight and I’m wishing you the best and I’m so sorry that I wasn’t the one you like and now I will lay this relationship to rest.
