my baby's in the white fluffy clouds

Let me add to the chorus of support and say: way to go! Congratulations for persisting in grad school and work as long as it made sense, and even bigger congratulations for realizing when it tipped the scales from "hard but worth it" to "counterproductive and possibly self-destructive." No grad program is worth burning out over. We're all told that. But it takes courage, clarity, and honest insight into your own needs to perceive when the scale is unbalanced and act to set it right again. You've done just that, where many have failed and paid for it. I'm proud to know you even indirectly, and hope you keep working on interesting intellectual stuff in the freedom of your own time.
