I'm 15 Years Old. I'm A Virgin. I Have Iron

I'm 15 years old. I'm a virgin. I have iron deficiency anemia and never treated for it because I mom said no. My symptoms are very strong and affect me every day. I've had my ribs overlap a few times for about 2 years now. I just want to know if there's anything wrong with that? Because I've been told by my family that it's very weird for a girl at my age for my ribs to do that and when they do it hurts really bad to the point where I want to cry sometimes. If there's anything you know that could explain it please get back to me.
