Major Life Change Event

It has been a while since I have posted a journal entry.  So how shall I say this?  Best to just spit it out.
 
About the time I threw my 2nd PE, I was taking much longer than normal to get my work tasks done.  And I was having problems with my critical thinking skills.  Finally my supervisor was concerned enough that he started some daily technical briefings.  At first they helped, but after a while they exasperated the problem.  Then my supervisor gave me a written warning with deliverable dates. This pushed me into a depression. 
 
ON July 1st I went to my GP, and we determined it was time to increase the dose of my SSRI.  When making these changes, it takes a while for the change to take affect, and my Doctor wrote a note but did not mention the time off.  So when I asked for the rest of the week off, it was rejected.  I was in a depressed mood most of the day, and when I heard that the time off was rejected, that pushed me over the edge.  I wanted to commit suicide.  I felt I was out of options.  I went out to cause a car accident, and a voice in my head (God, who else) said "you need help.  Go get it."  So I drove home and collapsed in my chair crying.  10 minutes later my wife drove me to the Emergency Department, and I checked myself in.  I was inpatient for 2 weeks, followed by 2 weeks in a partial hospitalization program.  The program let me go home at night and during the day I was in a group intensive program which involved daily check ins, followed by coping mechanisms and relaxation techniques.
I found the program very helpful, and this week I went back to work.  I felt apprehensive about going back to work, so this week was definitely stressful.  Today I determined that I am definitely not happy at my job, and I told my supervisor about it.
While I was inpatient it dawned on me very quickly that it was time for a career changing event.  Now it is more clear than ever.  The questions I am having is what to transition into and how to do it.
