Don't mean to sound judgmental (but perhaps I am a bit because your post is a trigger for me). Why are you not medicated? Did you choose to go off your meds independently? Or have you never been officially diagnosed?

In my judgmental opinion, if one chooses to go off meds, one should be prepared to experience the disease full force. It would be wise to learn coping mechanisms and have a plan of action before going off meds.

That said, and I apologize for being so judgemental, this is a huge trigger for me, you may consider going to urgent care, the ER, or call your GP, they may be able to give you some medicine to reduce/calm the effects of your hypo mania.

Good luck.
