Advice pls

Okay so I’m In a relationship with a girl I love I had a crush on her for a while we’ve been dating since 06/22/18 it’s now 08/7/18 so not too long and she’s really suicidal because one of her parents died and she thinks it’s her fault... I don’t really know what to do. It’s a lot of pressure for me sometimes, I’ve talked her out of suicide 8 times since we’ve been dating and Idfk I just wanted to rant maybe get some advice... We’re both dec babies and are going to be 13 this year... (Ik we’re a little young for dating) EDIT: She has therapy she says it makes her more depressed she hates talking about it.
