雅思口语P2 Describe a difficult decision you once made(文字版)

The decision was all about my weight problems in life. You know, a couple of years ago I used to be overweight, since at that time I was suffering from heavy workload and pressure of my study. Then I kept on eating all kinds of food in life, include the fat and high calories you know. Because of this, I even didn't have a photo of myself. You know, I was like a bit weird or strange when I found myself on the pictures and photos, very ugly. The other day, I made up my mind to make the change. I started to lose weight and I was planning to carry on it in next 2 years. It was tough for me. I have got no idea how to do it. More importantly, I didn't think that I could successfully make it, either. You know, I had to get rid of bad habit of eating, said no to my favorite cake, ice-cream and donuts. Besides, I had to take part in some training courses in the gym. Then I was thinking about it time and time agin. asked the advices from my friends, relatives and parents. About 3 weeks later, I decided to do so. 3 times each week in the gym, the healthy diet each day. Till now, I have been doing this for a long time, almost 2 years. My weight problem has been gone. So, this is the most challenging decision that I have ever made. That is it.
