A few days after the initial memory loss, I went to my doctor. He told me I had transient global amnesia, brought on by a combination of events. Just before I lost my memory, I was extremely stressed. I was anxious about my third-year exams. I had also just split up with a boyfriend, and I'd had a nasty stomach virus followed by tonsillitis. I felt physically and emotionally overwhelmed. The doctor explained that my body could no longer handle the strain, so my brain had closed down its "episodic" part, which is linked to emotional memories, times and events.
This little snippet reminded me how the mind is a funky place, indeed.
