It does sound like the party may have pushed youn inot some hypomnia, which can feel great at the time - especially with such a special event. But sometimes for us what goes up must come down, ie a plunge intoi depression. I was on SSRI's for6/7 years and they destroyed my life - I didn't know it all that time but they are contraindicated for me - not for all Beepers, but some. They would shoot me into hypomania/mania and then down into the deep dangerous depression and the mixed states, rapid cycling and panic and anxiety. It may be appropriate to ask about this.

But a mood stabiliser is definitely the go - with whatever other meds you are on.
