I'm Pathetic

This is a song about a guy who's suffering from depression and his girlfriend leave him. Pretty emo but whatever. It's going to be played on an acoustic guitar with some bass guitar in there too and sang pretty slowly. Let me know what you think.

I don't know what convinced you to pack up and leave,
Weather it was the state of my flat or of myself,
Either way i'm writing this to ask you to come back,
Because i don't want to be with myself,


I know i'm pathetic and i'd promise to change,
But i've said things like that before,
I guess now i can see,
Why i'm left staring at my floor,


That time when we went down the park,
We played like little kids,
Then i threw my self out of the pram,

I said i never knew what's wrong,
But playing on the grass never seemed my thing,
I said "i'm too grown up, let's go to the car",
Now i know, there's no where i'd rather be than in your arms,
And that grass, now it seems pretty ****ing green


I want to be by your side one more time,
Just to thank and apologise,
I know i'm pathetic and i'd promise to change,
But i've said things like that before,
I guess now i can see,
Why i'm left staring at my floor,


Every one of your birthdays, slipped out of my mind,
Into the same bin as our valentines,
Now all the numbers are burned into my head,
But they'll be gone soon when i'm dead,

I'm driving myself mad and i just want to die,
I could do with your face just one more time,
I'm too pathetic to come up with a plan,
To win you back like it's some silly game,
So i think, i'll pull the cartridge out instead,
I'll just pull the cartridge out instead,


I know i'm pathetic and i'd promise to change,
But i've said things like that before,
I guess now i can see,
Why i'm left hanging at your door,
