Hello and welcome to Healthcare Magic. Thanks for your query.
I can understand that it is very stressful to have a family member with an active psychiatric illness. Bipolar disorder
is a relapsing illness, which means that unless the person is continuously on regular medication (mood stabilizers), there can be relapses of the episodes of mania
Right now, since you say that your father is in the manic phase, the first priority would be to initiate treatment as early as possible. I would suggest that you take him to any psychiatric hospital with an in-patient facility, so that he can be admitted for a few days, till the severity of the illness comes down and till he is in a condition to be managed at home.
Wish you all the best.
