9．李紅減肥以后，感到身體疲倦、虛弱，不知如何是好，于是她寫了一封電子郵件向健康專家Burke求教．請根據(jù)下面內容，以李紅的名義寫一封郵件．詞數(shù)150左右．
原因：覺得自己太胖，體重不斷增加，擔心形象不美，有同學嘲笑．
過程：
1．去健身房，兩三次就放棄了，感覺太累也沒時間．
2．節(jié)食，堅持了大約一個星期，經(jīng)常餓得不能繼續(xù)她的學習．
3．悄悄服用減肥藥，一開始有效果，體重迅速下降，但減肥藥對她產(chǎn)生副作用．
注意：=1．詞數(shù)：150左右；
2．開頭和結尾已給出，但不計入總詞數(shù)．
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．
