After I talked to Elaine, Carolina and Bijal, and reading the comments that Anne, Lilith, Val, and Blanche left in the previous post, I feel much much better. Thank you guys, thank you so much for supporting me. I guess I was thinking too much and in a wrong way. As people who know me well, they know I am a pessimist, but from now on, I will try to change to become a optimist. I will try to have more confident to speak up. And once again, Thank you my friends, without you, I would be still depressed.
