I’m a 32-year-old woman, and I'm unsure how to support my partner, who is 36.

I'm in need of sincere advice. My partner is struggling with severe depression, stemming from a health-related issue for which he feels a deep sense of responsibility; I’d prefer not to go into details. Since we both work from home, it's reached a point where he frequently interrupts my work to express how overwhelmed he feels. He constantly fixates on the idea that he's "ruined" his life and is unable to focus. When he is less consumed by these feelings, he recognizes that he shouldn't burden me and expresses a desire to change. However, when he spirals back into those thoughts, it becomes a recurring issue. I have Borderline Personality Disorder, which makes it challenging to manage my own emotions. While I’ve tried to support him by letting him vent and offering my perspective, I'm starting to feel frustrated. I'm genuinely at a loss for what to do. He has mentioned that it may be best for us to break up and for him to move out, but he expresses fear about being alone, worried that he might harm himself in the future. This situation feels incredibly difficult, and I’m unsure how to proceed, especially since he fears losing his job if he were to seek help, and his family lives quite far away. **Update: He began taking antidepressants last week and is attending therapy weekly, but he feels embarrassed to discuss this issue with his therapist, insisting that no doctor can truly help him.** Any advice would be greatly appreciated. **Summary:** My partner is deeply depressed, and I'm feeling the weight of his emotional struggles alongside my own.
