Help my extremely intelligent bird

I bought an Indian ringneck a month ago and I'm having a hard time getting her use to me. I feel she is starting to suffer from lack of attention. How do I socialize with a bird that's scared? She has tons of toys large play area days without ever being locked in her cage.
The breeder said she would calm down and she hasn't and I think she's get worse. I've owned conures in the past and never had an issue. How do I stimulate her ? Get her to socialize? Is she out of my league?
I'd rather figure it out then rehome her. Please help.
