One thing that is important is to 'do stuff'. Posting here, walking, work, writing and listening to whatever tunes move me at the moment helps me out.
I happen to be a depressive, who lives with another depressive. We express ourselves in pretty much the same way you two seem to do. I always think she is overreacting, and feel the need to retreat. She feels she cannot express her emotions except in ways that I see as extreme, so therein lies the dilemma. I always think it is me, she always thinks it is her. Neither of us feel we can really talk to each other.
I did go for therapy. Cognitive behavioral Therapy (CBT) which was amazing, and quick. I never accepted drugs. I'm not sure what sort of therapy you went for, but regressive therapy is really not good for depressives. It just gives them ample time to dwell on the past, rather than think about the future.
My take these days is that it really isn't so much about how one perceives themselves, but more about how they communicate their feelings with others. Your hubby might be a bit depressed himself, and not know how to express it in a way you can understand, just as you feel about him.
One thing I've found that works is to set boundaries when you talk and/or argue. It's a bit like S & M

. Partners react in different ways to perceived slights or threats. Sometimes we all say really stupid things. Make a rule that if emotional buttons are being pushed, the one who feels pushed takes a deep breath and says, politely, "you are pushing my buttons." When either partner hears that, it's a 'red alert' to calm down, listen, and start talking like adults.
One other thing. Don't fall into that trap of feeling you 'need' to convince him it's 'you.' It takes two to tango, and compromise is the solution, not self-deprecation. Also, don't fall into the 'I hate it when people don't like me' trap either. Thankfully, for us depressives, that is generally not the case. Love, concern and frustration from those close to us maybe, but nothing more, and it's really all about the love. Think about it this way, if he didn't love you, he wouldn't get frustrated, upset, or think that it's 'him'.
Just coming full circle here, to your first paragraph, never assume he 'doesn't understand' or does 'nothing to help the situation', and then go on to ask how you can convince him 'it's you, not him'. Mixed messages, but very in line with depression. You have to start thinking that it's actually about both of you, and find a middle ground. Sorry if I'm rambling, it's just that I've been there, and still live with it.
