Pick me up Or let me fall

Its complicated, i cant explain it,
you make me tear up , you make me sad and all alone, and like know one can get close,
cause in the end, they love and leave,
why don't you save me the tears and go,
come back, i cant live without you,
its difficult enough, i don't know what to do,
you tell me you like me and then lead me to believe it, then deny it, it hurts, I'm done I'm over it,
no I'm not, you confuse me,
but it makes me fall more and more,
will you please pick me up.
