里面的 I almost went bananas 的意思是？
附上下文:
GOING POSITIVE
I always wanted to look like the slim girls on TVeven though I knew that it was impossible. I worried about my weight and triedevery new diet I read about online. I tried no-fat, low-fat, 5:2, only bananas, no bananas—Ialmost went bananas, too.
Then I read an article that said instead of asking “AmI fat?” I should be asking “Am I fit?” I had no idea a letter could make such adifference! once I started thinking about fitness ratherthan weight, thingsbegan to change. Instead of saying “I want to lose three kilos”, I wouldsay “I want to run two kilometres in eight minutes” or “I want to be able to do30 push-ups”. Rather than cutting out the foods I enjoyed, I addedhealthy foods to my meals. I could still have a burger now and then, but Iwould add a salad or an apple.
Finally,I sTOPped comparing myself with actresses and models andlooking for things that were wrong with my face or body. Instead, I made alist of the things I liked about myself. By being positive about myself and mybody, Ibecame both happier and healthier.
