My partner had a week of mania and psychosis over the holidays (along with a suicide attempt); I am currently forcing myself to eat as he is currently having a manic episode (with rapid cycling). These are my coping methods:
​
1.) Put myself on a strict schedule: go to bed at 9; wake up at 5.
2.) Meditate for 45 minutes in the morning
3.) EAT (healthy food)! Even if I feel sick to my stomach.
4.) STAY AWAY from alcohol or other psychoactives to cope (I do consume caffeine, but not to cope with uncomfortable emotions)
5.) Exercise even if I really don't feel like it; I force myself to exercise 5-6 times per week.
6.) It is important to spend some time alone to self-reflect, but do not get bogged down in rumination and do not perpetually isolate yourself; make sure to reach out to family and friends for support. Something I regret is not asking for asking several months ago, so make sure you reach out and ask people (maybe even his family) for help.

Awhile ago, I took a course online to develop resilience: https://www.coursera.org/learn/positive-psychology-resilience

Hopefully this helps.
