Well, of course she is scared to try new things. It sounds like her family treats her like a baby, when she must be at least 22.

It's pretty hard to fight the family. They've been working on her all of her life, and you only had 4 years. Until she's ready to break away from them, you're probably not going to have much luck.

Just remind her that you're there for her if she needs you. Maybe she'll make a decision for herself.
