confuse...

these few days always think nothing...
think very much but don know what i'm thinking...wanna be crazy...
he always advise me that don think toooooo much,
but i can't!
when i'm nothing to do,i will start to think...
think about me and him...
-am i wrong that i be with him?
-will i feel regret that i be with him after this?
-what will i do when he want to break with me?
-will him treat me bad?
and many many things............
who can help me to solve it?
i really feel confuse now...
