Summer lethargy

From yesterday, I have no appetite. Is it lethargy? or broken heart? Broken heart's feeling is like this? Hmm... maybe this is so. It can't know without experience, even if I read a lot of romance book much more.
It maybe better to leave her alone now, so I cant send E-mail or call. I wanna do nothing now. But I did not notice till now that I love her. Why do I love her? Year, but she is different from other girls at all. she is honorable and I respect her. So, I love her.
How to tell her my feeling?
But at first, I have to become much more brilliant human with many more drawers.
