I’ve been together with my now fiancé for about 3 years now. I’ve noticed she’s gotten a lot worse when it comes to her depression. She’s had a lot of traumatic things happen in her life that causes her to have extreme mental breakdowns. Back in high school the root of her depression comes from when she was Sexually assaulted. There have been many things in between then and now that have happened and it has only made it worse for her. 

I have tried everything I knew, from giving her personal advice and life experiences to help her with multiple therapist, nothing seems to work. She’s been diagnosed with non-combat ptsd and major depressive disorder by multiple psychiatrists. 

What I’m trying to get out of this is some advice on what the hell I should do to help her. I really want to see this girl blossom and it pains me to see her this way. She says she can’t just simply stop thinking about her traumatic past and just bottles everything up till it explodes. 
I’m a firm believer in mind over matter but I just don’t know how to go about explaining to someone how it works and when it should be utilized. 

If someone could help it’d be greatly appreciated but if not I completely understand as this is an extreme case.
