haih...
I really dont know why am i so weak compare to last time..
I used to be very strong emotionally but not at the present moment..
I really cant let go things off me easily and as well as i cant forget about her..
Is really suffering to think of someone that had left you and knowing that he/she is ignoring or avoiding..
I am seriously sick of it and i really want to be strong and keep things going on smoothly..
But at times, when i am too free,, memories will play by itself without any command..
Huh!!!
I know that i am kinda dumb and stupid for not forgetting things fast..
Feel bad about it too..
what do you think i should do??
Any suggestion?
