thoughts that defy logic

I know they say not to think about it,
That logically everything is alright.
But sitting all alone,
in the cold, dark night,
Is enough to make me lose control,
Enough to make the feelings and thoughts,
Squirm their way into my head.
Logic can't stand up to those feelings and thoughts.
No Friends, No Love,
How can logic stand up to that?
World better off without me,
No one would miss me.
Logic says these are all lies.
But in my heart, they are true.
In my heart,
No one is there for me,
No one cares for me,
Maybe they would be better off without me.
Logically, I know the truth.
I just can't shove the thoughts and feelings out of my head,
Out of my heart.
