Weakes Guy Ever Lived

I cannot take it liao ! I am stupid, brainless, useless, whatever lousy words can describe me. I been liking this gal for a long time. Everyday I would automatic think of her. Ask myself things like how is she today, will she want a lift from work if my dad's back early, have she eaten etc. N the best part of all is I have been telling myself to stop it else I will give trouble to myself in the future. Sorry guys but I think im the weakes guy ever lived. Haiz. I hate myself being like that. Y can I cant just tell myself move on. Even I ever asked her before weather I would stand a chance. She replied to be better off as friends. What's Wrong with me. Sibei useless. Utterly disappointed.
