answer:If I’m doing the math correctly, your disastrous first semester was over five years ago. Let your record speak for itself. What matters on your grad school application is your GRE scores, excellent gpa for sophomore, junior and senior years and the quality of your essays (assuming your program is in the Liberal Arts and not math or science). Should anyone ask, which is unlikely, skip the “overwhelmed” and simply say that you were immature. Then move on to your successes. Bravo, by the way, given your earlier history that you did mention several years ago.
