I think so,too.
relax yourself and try to share more with your friends . It may be helpful to listen to soft music after busy work.
well, take good care of youself lest we are worried about you.
i admire you even though you can not have a good sleep , but you have owned a group of close friends . so come on and go on adjusting yourself . we all think you can succeed.
if you feel better, please tell us.
