Thank you for your reply.
So, you asked her what made her feel different.
She responded she knows she is different. She did
not articulate it further.
You may try to ask her what makes her feel different from her peers again.
She may have a clear answer or not.
For some reason, she may not be able to say it. For example, she may not be aware of what makes her feel different. She may feel like she should not talk about her skin color comparing to her black peers subconsciously as she attends a predominantly black school.
It's common for children of her age not to be able to verbalize all her feelings and thoughts.
She may also be emotionally younger than her age.
If you are concerned about her feelings or behavior later, you may take her to a child psychotherapist in your area.
She may see a child psychotherapist specializing in play therapy weekly for 3-6 months. Child therapist may help her to explore, express and process her big feelings and thoughts about self and/or others, which in turn may help her to feel less anxious about self.
Please let me know if you have more questions or I have overlooked any. Warm regards,
