Why these thoughts...

Head spinning, so many thoughts
Why does this always happen to me
Right when things are going good
Something like this had to be

I don't understand, I am so confused
I thought I was better than any of this
I just want to finally be happy with her
Or was there something that I missed

Thought after thought keeps running through
She deserves someone better than me
Why do I look so down upon myself
When me and her could forever be happy

I think so lowly of myself
And I really don't know why
She means the world to me
But I don't feel like a worth guy...
