Diagnsis is not really that important. I wish I was never diagnosed borderline cuz it really does sucj, I've had therapists not work with me cuz I was diagnosed as borderline. Its so hard to manage like you said my moods are all over the place. Im not married but I would prolly do the same behaviors if I was married. So really dont worry too much about a diagnosis cuz really the thing is to manage the symptoms not get a diagnsis. I know they need to dx for insurance reasons cuz in the DSM there are numbers like 301.8 and the insurace companies need to know about this so yeah anyway good luck to you and now im going to sleep.
