Thanks mate. I normally get through it all fine eventually, just makes for a shit few months until it settles down. Hope the wife doesn't go through it for too long, it's a horrible way to feel...
She was in a pretty bad place in November / December last year. Started seeing medical help in Jan and has been on the up since then. Thankfully she responded well to meds and we found her a good psych. A lot of her issues were triggered by her work situation and we've also managed to find her another job. Basically, she's not quite out of the woods yet, but she's on the fringe.
Her biggest worry now is finding another trigger but the psych is working with her to understand what they are and how to manage her emotions when they come up.
Hopefully, in time she may even be able to get off the meds... One day.
The whole situation has really opened my eyes though. Can't say I have a better understanding of what goes on in her head, but I've seen how totally debilitating it can be.
