Mentally supporting someone with Schizophrenia/Schizoaffective can be tiresome, draining, & unpredictable. You DEFINITELY need to consider your needs. Even when you *are* taking care of him, he believes you are against him... So I don't think it's of any consequence to his perspective whether you take a mental break for yourself, because it sounds like his paranoia is pretty static. But you cannot sacrifice yourself for the sake of someone else... That is unwise & I am sure that, if he were in his right mind, he would not ask something like that of you. This is just my perspective, being someone who is trying her hardest not to be incredibly burdensome to her doting fiancee. : )
