Advice from mental professionals and associates

;-0 :-) ;-p
I am a therapist and I am married to someone who has been diagnosed with schizo-effective disorder. It can be a challenge because I feel like I constantly feel like I have to be in "therapy mode" or "perfect" to keep the peace. I understand that it's not easy for him either, but I feel drained. My question is, are there mental health professionals who have a SO with a mental illness. How do find balance in your relationship. How do you support him/her while not being "on" all the time. How did you learn to be vulnerable with someone who seems to get overwhelmed easily.
