Two Weeks After Discharge from Hospital
Shortly after I was discharged home from hospital in November 2015 I had a review meeting with the brain surgeon who had operated on me. We discussed my intent to return to work (as an IT security consultant) and he commented how I was being sensible in deciding to wait a further two months until the New Year of 2016. Despite desperately wanting to retain my purpose in life by returning to professional work, it wasn't until July 2017 that I did so - a further eighteen months later.
Looking back on this period with several years of hindsight I still find it impossible to explain how I felt. I can't describe my limitations which made it hopeless for me to consider returning to work. Furthermore, I can't describe what changed in me that eventually facilitated my return to work.
