9．李红减肥以后，感到身体疲倦、虚弱，不知如何是好，于是她写了一封电子邮件向健康专家Burke求教．请根据下面内容，以李红的名义写一封邮件．词数150左右．

过程：

2．节食，坚持了大约一个星期，经常饿得不能继续她的学习．
3．悄悄服用减肥药，一开始有效果，体重迅速下降，但减肥药对她产生副作用．
注意：=1．词数：150左右；

Dear Burke，
I have got a problem and I need to ask for your help．I feel I am a little too fat．What's worse，I am putting on weight all the time．I am very worried about my figure and how I look．I even fear that some of my classmates laugh at me．
At one time，I tried to work out in a gym two or three times，but I finally dropped just because I had no time and always felt very tired after doing exercise．Once I tried going on a diet．However，after about a week，I could not go on because I felt so hungry that I was not able to continue my studies．Then I took weight-loss pills in secret．Shortly after，they did work and I was losing weight fast．But I felt tired and weak sometimes．
I know those pills usually have bad effects on our health．Thus，I don't know what I should do．Could you give me some advice？
Yours，
Li Hong．
