Can I consider this as an achievement?

Before, I was a 64 kg. and it doesn't really matter for me. I don't even care whatever my friends calling me by that time. And it also doesn't affects me. But, as time goes by, I noticed it by myself that everytime we were taking photos, it's just like "Oh my! Why am I so big?" I always asked myself bout that. And ofcourse I knew the answer. Because I really love eating everywhere. Especially if it's a box of pizza, a bunch of fries and a huge size of burger. Then one day, I realized that I need something for a change. Not for the sake of everyone, but for myself. Month of March, I went to gym and that lasts for about 3 months. Till the month of June. And now, I weighted 52 kg. I remembered the first day of class, most of my classmates were shocked when they saw me. And until now, I can't really believed that many people asked me what did I do during the summer vacation and I lose almost 10 kgs. Lol 😂 Is this an achievement for me right?
