Hypomania

I'm bi-polar II, have severe cervical disc pain and have generalized anxiety disorder. I'm coming off of the longest and hardest hypomanic state I've ever had. It coincided with PMS, which always turns me into an angry, weepy mess. It's been almost a month of floundering while pretending everything is ok. I run a small nonprofit so I had to put together a large fundraiser while feeling like I'm losing my friggin mind. Now the depression and anxiety are hitting and it's sapping my energy and bringing my grief back from two major deaths in my family in March. But, I can't show it and have gotten good at pretending I'm ok so the nonprofit doesn't lose support. As we help a hundred plus dogs a year and it would be selfish to jeopardize it because I'm physically and mentally broken. Im in therapy, on enough meds to knock out a horse and still cant sleep. How do you get out of bed and move forward everyday while hiding such a big part of you without that hidden part eventually imploding?
