Nong needs to go to doctor for her depression and her anger which always happen before periods. Every time she is angry and run away it is 10 days before her period . This is hormonal problem. You and aunty lilian need to take her to doctor to help her fix this problem so she can be happy again . She needs her family support which I jnow she will have from all of you. Make sure aunty Huen not to mad at nong .And make sure mum and dad not worry to much. When nong go back let me know how she is . Thank you Rob
