A little background information: I am positive my boyfriend has depression (based off reading the warning signs for depression article). A few weeks ago it was something he was trying to overcome by himself and something we could talk about. It has now gotten worse to the point that it is basically breaking us apart because he is isolating himself, feeling worthless, and highly irritable with me. Our relationship is in a fragile state so it makes this even harder to deal with. I told him to see a doctor, but he thinks it has to be a psychologist/psychiatrist (which is health insurance doesnt cover) but I tell him to start with his primary first. He doesn't listen. It is a long distance relationship at the moment so I can't drag him to the doctor myself. He is not suicidal from what I know, but I do know he does have reckless behavior tendencies.
Questions: How can I help him? What are some techniques of communicating to him that won't make things worse? How do I help the relationship when he is like this?
