Having a life-long love affair with Japanese Zen, and a ten year zazen practice, the most useful insight for me comes from Claire Gesshin Greenwood's book, Bow First, Ask Questions Later. <quote> Most teachers of Zen, in Japan at least, will tell you that Zen is "not about thinking," and that practice is something you do primarily with your body. </quote> Soto Zen's practice of Shinkantaza, 'Just Sitting' fits well this. It's the posture, stupid.
A few more snippets from Gesshin's book: In the Zen tradition especially, there is a lot of emphasis placed on "not thinking." In "Universal Instructions for Zazen", Dogen Zenji wrote, "Think of not-thinking. How do you think of not-thinking. Non-thinking. This in itself is the essential art of zazen."
So generally (in Japanese Zen) the advice given is to just practice without trying to understand what is happening, because the only way to actually learn something is to engage with the thing itself without adding your own idea. If you add your own idea, then you are just engaging with your idea, not the thing you are trying to learn. I should add that this is all advice that I have personally received.
The nature of the illness varies somewhat over time. The panic attacks only seemed to happen when I was in a room with a large group of people. So quitting school largely removed me from those situations.
I was diagnosed as Bipolar 2 in 1997 by a psychiatrist in Manhattan, where I was living with my girlfriend. I started having true bipolar symptoms in USAF Basic Training but made it through (talk about rough), then years later working as a developer, I got to a point where I could just not deal with people. One of the signature characteristics of bipolar (and other similar disorders) is some form of paranoia. People at work would make some mild critical comment and my head would be spinning for days full of anger and fear and pondering what I should have said. The NY psychiatrist asked me just a few questions: 'When was your first clinical depressive episode' (19), and 'are you second-guessing yourself a lot' (Yes. A manifestation of paranoia as noted above).
How did I ultimately deal with the disorder? Wonder drugs! Zyprexa since 1997, Wellbutrin for many years, and lamotrigine, a mood stabilizer. Being bipolar is not something that I notice much anymore.
One thing I would mention for anyone who is listening and suspects they are bipolar: Bipolar people are vulnerable to trauma and PTSD. What helped me was another miracle (IMO), EMDR. A single one hour EMDR session with a trained therapist can rid you of trauma that would take a year or more of talk therapy to accomplish.
Not looking to compete for the crown, but I have been involved with software development on and off since 1970. I started college in 1969, and really loved my liberal arts and social science courses, but began having panic attacks in class (I found out many years later that I was bipolar). My hail Mary move was switching majors to 'Business Data Processing'. My thought being that programming would give me a salable skill the quickest. We were doing JCL and COBOL programming on the school mainframe using punch cards. The panic attacks continued, and I dropped out of school in 1971. In 1975, I enlisted in the US Air Force, and spent six years working in Signal Intelligence. I have been part of the defense contractor corps (aka Beltway Bandits) since 1981, and doing database development/admin continuously from 1988 to this day. I'm 69 now.
I took a copy with me to USAF Basic Training in 1975, where of course, I couldn't read it. Found it in the Lackland library. Kept me sane during those weeks. It still shapes my thinking today. My first bike was a 305 Scrambler, the off road version of Persig's Honda.
