take a vacation.  as far away as possible.

maybe it's time you should disconnect for a while, and take a
rest.  get your meds straightened out and have some no-stress
time.

Sorry you are having  a hard time. Negative environmental triggers
certainly do not help bipolar.
I have mood problems that are more reactive and labile than cyclical ie
more in line with borderline personality disorder but also have definite
  bipolar type behaviours.
Doing the best for me as a mental illness sufferer and for my wife as a
carer  is often a very different thing.
One of my major problems is with meds.I am supposed to take olanzapine
10mgs which does help with the dysphoria i am prone to but it makes feel
very sedated ie zombified  and then i am not as alert as i should be re
providing care for my wife.
Looking after a relative with dementia of any kind is very stressful
even if you do not have a mental illness.When my wife was in hospital
being assessed the majority of relatives who had been caring for their
relatives prior to  them being admitted were on tranquilisers due to the
stress( they were not people who were mentally ill  themselves)

Boydette, you have to take care of yourself first, because if you can't get
yourself on track you can't possibly be any help to anyone else.    Take a
break and don't feel guilty about it.  You need the time right now.    Hugs
to you!

Ronny:
I like the advice you've already been given in this thread to just take
a break and care for yourself first right now. And hey,that's not being
selfish! :-)
