How did it all begin?

This time I could say it came suddenly. Secretly I think it built up slowly over a long time, but it all came out at once.

There I was, at work, just back from holiday, a girlfriend who loved me. I do a lot of creative stuff, and I'd been on a roll with my writing and my music.

Then, crash, can't cope, can't study, can't work, can't cook even, want to cry constantly and do so. Luckily my girlfriend still loves me.

There is a lot more background, past stresses, unresolved commitments, but I'm wondering whether others had it like this? Not a creeping syndrome but a breakdown.

I have to talk to a doctor about it all tomorrow, and my memory has gone quite poor, so I'm just trying to get some theory I can use to support my thinking as I try and work out the sequence of events.

Anyone?
