Wow, I haven't experienced that for 6 yrs. and so much the same as you stated. For 8 months I'd only need to sleep 2 hrs per day,attended college part time,cared for the home,and loved shopping when time allowed,I must admit it's the greatest feeling (mild mania/hypomania)I've ever had.
felt,but sadly we know it doesn't last,things deteriorate.
I melyed down,fell apart,fallen in such a depression,I developed suicidal idealities. Some of this may be the heredity thing,but lots of it was triggered from someone being unloyal,which freaked me out. Soooooooooo, I agreed with my T and pdoc who then DXed and started treatment, I'd volunteerily sign in the hospital,after 10 days I was stabilized on meds and followed up with therapy and pdoc visits for med monitoring. Up until this age and event (someone breaking my heart) I had never had any symptoms nor did anyone ever think I had a problem.
It can be strange when all of a sudden Bipolar attacks you.
