We can only work with ourselves. If you do interrupt your husband and/or do not like to argue with him, you can only help yourself learn not to do that. If you are afraid he is going to pack and leave, he may or he may not, no way to tell but you have to deal with that within yourself, either way.

Are you seeing a counselor at all or just on meds? If you cannot or do not wish to afford a therapist, I would go to the library and get a book or two on working with your ADD, or anxiety, or depression on your own and see what you could change about your own feelings and actions so you are more comfortable and feel more secure. No one else can give you self esteem or security, that is our own job to do for ourselves.
