I already had sleep issues and high anxiety even at 4 or 5 years old. My early 20s were bad for me though. That was when my eating disorder was really bad. I don't have fond memories of those times, and I had 2 psych hospitalizations.

My mid 20s were good though. Even if I wasn't quite on the right medication, I was still able to think quickly, get a scientific article published, get my M.S. I probably looked my best too. In high school, I was a little overweight, but not bad, maybe just around 10 lb. By my mid-20s I'd gained back enough weight that I looked good, and after the eating disorder, my set point weight adjusted a bit lower, more in line with my bone structure (which is small). I have professional pictures my husband and I took before our wedding in 2004 where I was pretty stunning. At that time, my hair was longer, and I looked a lot like Grace Kelly did at that age. Once I watched an old Grace Kelly movie, and it was weird, like seeing my younger self act on TV. Now, though, I cut my hair short, and I long distance run and have a leaner physique and need to gain weight again, so the resemblance is gone.

Though honestly, if I could have the intelligence and creativity I had in high school on top of my mid-20s looks and my current life experience lessons (without having to actually go through them), that would be most ideal.

You can't have it all though.
