Is writing about my weight loss journey on college apps a good idea?

To give an idea, it really affected me because i gained all that weight in like a month or two (honestly idk how). It was a really significant amount of weight on me, and on top of my deficiencies it really affected my mental health as well as my ability to focus. I would fall asleep at the most random of moments during class (one time I almost fell off my chair), even though I would get enough sleep. It really weighed me down, both physically and mentally.
