Their depression affects us but analyze: what's my role? Map depression impact: their struggle vs. using depression to excuse bad behavior. Calculate: support I'm giving vs. enabling vs. my own mental health. Show me the depression reality: support vs. becoming their therapist vs. losing myself. Give me the boundaries: I can support this way, can't accept this. Include: whether I'm supporting or enabling, if depression excuses their treatment of me, and whether I'm drowning trying to save them.
