emotional suffering

No matter how much I try, no matter how much I love, I always doubt
I don't know when you're sirious, what you really think
you seem to change your mind about me all the time
and even if you think it's stupid...I care. I care way too much.
One day you say you do, another day you same the same thing to another person
and you come back after some time...again.
no matter how much I try, I feel I'm doing something wrong
but I think I'm the one who's hurt after all...
To one and only....You know who you are.

Emotional crap~
