She definitely has self-esteem issues. She has felt like she lives in the shadow of her cousin. I've been trying to tell her that she's not behind in life, but she truly believes she is and I'm not sure why. She actually just graduated (on time) with a BS and has related jobs (still looking to start a career though). She is panicking about the future a lot and I feel like nothing I am saying is helping.
