Just tell me how and I'll make everything right

I have heard many times before,
There are more fish in the sea,
But how do you just let go,
Of your destiny,

I try to tell myself I'll be okay,
Though its only a temporary healing,
Can't get you off my mind,
How can I rid of this feeling,

I admit I messed up,
It's all my fault,
I can't fix it,
To you and me I've been an insult,

You always dodge my glances,
Wish I were dead,
Just want me gone,
Turn your head,

I can heal all your pain,
Just give me a ring,
We'll chat for hours,
Want to be your everything,

I only want to see you happy,
That is my goal in life,
More than anything else,
Even having kids and a wife.

This is the situation in right now and i think its why this girl i really like doesnt like me and ya...please tell me what you think
