I quit in May, and since then have hiked the Appalachian Trail and just landed in New Orleans. I'll do a little part-time research work but my main goal is to write a lot and play music.
Before I left, I was depressed, and now I'm not. IMO everything else is totally second order to not feeling so darn bad all the time.
My plans extend to about the end of this current month, and then, we shall see.
