This book addresses a lot of these issues in broader sense, so it applies to all areas of life.
Two favorite piece I like to re-read when I have these moments.
+ The Secret to Success (this one is my all time favorite): http://www.thecrimson.com/article/2013/5/30/secret-to-succes...
+ Daring Greatly by Brene Brown (http://www.amazon.com/Daring-Greatly-Courage-Vulnerable-Tran...)
I can already see that you have so many of the skills described in Brene Brown's book. Keep fighting the good fight.
