Do you have plans to live in the same town in the near future? LDR can be very stressful.

Personally, I would not want to be in a relationship with someone who diagnosed me with a personality disorder. That's an incredibly inappropriate way of resolving a disagreement. You will never win an argument with him if he just ends it by telling you that you are crazy. Maybe I am misunderstanding that because you do say that you guys used to joke about it before.

I don't think your depression will go away if you break up with him or that he is the cause of it. The stress of your unhappiness in the relationship definitely contributes to the misery, but if you were feeling whole (for lack of a better word), you would probably break up with him or confront him instead of lying in bed. I am not sure if this is coming out the way I mean it --- I just mean that when we are depressed, our reaction to stressful situations is often to lie in bed, but if we weren't depressed, we might take action to change our circumstances. So it isn't the stressful situation that causes the depression, exactly. That's the way it seems to work for me, anyway.

What's stopping you from ending the relationship? Why do you question doing that?
