What is the most appropriate nursing diagnosis for maria based on the assessment of her emotional and social concerns ?

10-year-old Maria’s parents express concern that she has become more withdrawn and isolated from her classmates over the past few months. Maria used to be more social, but now she seems to avoid group activities and prefers to stay by herself during recess. Her parents are also concerned because she has been having trouble sleeping and has been getting upset over small issues at home. Maria’s parents are unsure whether these changes are due to school stress, family issues, or something else.
