in the blink of an eye

Life changes so fast at my age. Your life can take a complete 360 degree turn from semester to semester. Your apartment changes, your roommates change, your classes change, your relationships change, your opinions change, your testimony changes, your major changes, and unfortunately sometimes your weight changes. It's hard not to compare your current life with the way that life was a couple months ago. It's hard not to miss the way things used to be. It's hard to think that the way life is now could be completely different in what feels like the blink of an eye.
