Yes, lupus can cause depression, but this sounds like it could also be situational depression. Seeing a psychologist or psychiatrist might still be a good idea, but I wouldn't assume its lupus-related at this point, if you didnt have a problem before this. Does your doctor know this change in mood coincided with breaking up with your boyfriend? I think that's an important detail to include.

Good luck, I hope you feel better soon in any case!
