Tomorrow is my company's party.But I am so nervous .How do I should do?The nervous how to overcome  it ?I know I am lack of confidence.It just the singing.But I really so worried about it.sylvia  is my colleague,we will singing together.She already resigned the job,the last five days,she will leaving here.It means she'd not stay them same palce with me and  she can't company me any more.So sadly.Any way I wish she can be a succeed teacher.keep warm and happy everyday.
