Same as the above. Had a similar episode about 3 months back but the worst was while at Uni.

For me it gets to be an almost dream like state with narrowing options. It's like all rationality and resolve go out the window and I become bombarded with intrusive thoughts and a kind of notion that it's ok to just stop.

Is surreal and at certain points feels completely right.

Obviously I don't want to give real term examples as that would be trigger central.

Suffice to say at the time it becomes normality... But once it abates, to know that is where I was at is scary as hell... Like a totally different person was inhabiting my body, rather than the me who is rational, at times motivated and has dreams and ambitions for the future.
