I don't know what to say to my husband anymore. What to say or what to do.

He is down with severe depression. I do my best but it doesn't work. I'm going down with him even if I hide it from him. I can't get him out of it, give him hope, use his willpower. I just don't know what to do anymore. I'm here for him every second of every day and night. He is on anti depressant already. There should be something else I can do but what? I'm loosing my way too.

I have a strong willpower but i'm loosing it.

Thank you!
