Reddit mentions of Why Smart People Hurt: A Guide for the Bright, the Sensitive, and the Creative (Creative Thinking & Positive Thinking Book, Mastering Creative Anxiety)

I have a list by my home desk of things I can do:

• Boost serotonin: reminisce about a fun trip or good time
  
• Boost dopamine: create a bucket list or to do list
  
• Boost testosterone: Starfish pose for two minutes
  
• Boost oxytocin: cuddle for ten minutes
  
• Boost endorphin: go on a walk
  
  I like it because it's based on brain chemistry and they are easy to do and keep me from spiraling.
  
  I also really liked this book Why Smart People Hurt and have really liked other things by this author. Specifically the parts about finding meaning and enjoying achievement because I feel like those are my main blocks to fulfillment.
  
  Also this holiday I had a kind of break through for myself. It seems obvious but it really hit me hard. I was just relaxing and playing games on my tablet when I got the start of that "I'm not being productive" depression. Then I just thought to myself: I spend so much time being stressed, worrying, problem-solving, I work two jobs and have been in school, I'm going through a really tough period of my life--so what if I sit here and just don't be in stress for a bit? It really helped me put things in perspective and see another way to be kind to my mind and body.
  
  EDIT: oxytocin. No, I'm not cuddling oxycontin.

On a similar theme there's a nice book on the problems of being smart, Why Smart People Hurt (<- that's an Amazon link - this subs' CSS hides links!), by Eric Maisel. Not being quite good enough for the intellectual problem(s) you've chosen to solve, problems with being understimulated, so you turn to drugs + alcohol. The book is quite unique, I haven't seen what it says anywhere else.
