numtopain - In my head Lyrics

I said lately, i been sitting in my room on the daily
Thinking bout some things, got me f*cking going crazy
Flippin through these pages of my life, i'm i fading?
And she found someone, hope he makes you happy
I know I'm not the one
You coulda stuck around, but you left me now I'm numb
Got a broken heart, reminiscing bout a fun
And it's been hard sometimes,
To keep you right out of, my f*cking mind
Why'd you up and leave, i been going out by myself
I don't need you yea, i got myself
Yeah that's all i really need
