đź’™Relationship + depressionđź’™

Been in a relationship for 5 years and my depression is at its worst, I've haven't felt this kind of unmotivating, hopeless, careless sadness before for so long. What my question is, what do you do in a relationship when you have depression? Obviously if you can't make yourself happy, how are you supposed to make another person happy? Is my boyfriend supposed to try to help?
