Turnaround Essay Thoughts?

I graduated with a low GPA from Georgia Tech studying Bio-medical Engineering, and I'm wondering if I should add the following essay to explain my poor GPA.

High School and First 3 semesters in college: Made some very poor decisions in high school and college that kept me from focusing on academics (mostly too much partying and laziness but I won't go into detail).

Focused the next semester and did pretty well, even earning an award from my peers for the turnaround to my behavior and study habits.

Next year, I improved to just an average student. Obviously my previous struggles weren't focused around academics, because I made some sweeping changes everywhere. I devoted a lot of my time to philanthropy activities and getting involved on campus as a constructive way to spend my time.

With three more semesters to graduate, I made the decision to not stress about my grades and focus on something I could excel in. Instead of becoming just an average student which to me was the best case scenario if I focused on academics exclusively, I was hopeful that I could take on key leadership positions on campus and demonstrate to future employers that I could be extremely successful at managing projects and people. I was very successful at achieving what I set out to do, but my grades dropped those last semesters to a 2.0.

Obviously, I'm headed down a better path now. My other essays will discuss more about my leadership experience and how I am using my previous mistakes to be an example for high school students now. This statement would just be added to account for my low GPA. I am not sure how some would react, but it's the narrative of my life in college. It's not your typical "growing up" statement where everyone starts doing better academically once they manage their time. It doesn't show that I can handle the course load, but I did graduate from a rigorous school and did pretty well on the GRE.

Any advice on how to handle this low GPA would be great. Not including a statement about why my GPA was poor didn't seem to be an option with the admissions counselor.
