Hi Jordan087

From my experience it can be difficult for all parties involved when talking about suffering depression, maybe your fiancee feels frustrated with herself because the situation is new between you two or because she just doesn't know what to do to help.

Have you thought about going to the doctors? Or to a therapist? It can be a great relief to talk to someone about the way you feel, even if it is a stranger at first and it's loads better than keeping it all to yourself.
