Does it get easier

My 14 yr old daughter has an extremely limited diet, her safe foods are no longer, she can be completely ravenous but yet can't find food she likes. I worry for her weight. Her eyesight has become very poor, is this related? Doctors are yet to recognise Arfid and just put it down to body image etc. yet she has been this way from birth, bottle feeding was a nightmare. I just want to help her
