too much to handle

How can I go on as if it doesn't bother me? How can I pretend nothing is going on? Maybe nothing is but there is something really bugging me about this. That I can't seem to let it go. Can't seem to get it out of my mind. Can't seem to let it NOT affect me.

I tried talking to u about this. I tried making u understand. But u just brush it off. Fine. Brush it off. But mind u, it's not making things better. Now u just left me alone with the million thoughts occupying my mind 'til I can't think straight. I feel I have lost perspective of myself. Of u. Of us.

It's not that I don't trust u. I do. But she is a total different story. And your history together. How can I challenge that? Am I just a temporary substitute 'til she changes to suit u?

Because that is how I feel atm. And I think I really deserve better.
