A.C.
I am so sorry to hear about your daughters hardship! I know how heartbreaking this must be for you. I have a daughter about that age as well.
As a young girl, I suffered horrible self esteem. I went through a very gangly phase with bad hair, braces and glasses (ha, didn't we all!) but it hit all at once and, for those reasons or perhaps other reasons, all my good friends decided I could no longer be in their group. I was no longer allowed by them in their yard (next door) and I remember being very lonely. Their words and actions were very hurtful. One thing my M. did that really helped was to do her best to distract me. She took me everywhere that summer; we were always away from the house doing fun things. Now, that really may not be feasible as it is not vacation time, etc, but it may help to keep her surrounded by people who treat her kindly. Can she spend some one-on one time with a beloved grandparent or aunt? Can you take her out on a M.-daughter date? go to the library, let her help with the shopping, etc. Give her lots of praise and love.
I would probably talk to her pediatrician as well and he/she can help determine whether she needs additional help. Good luck! Let us know what happens!
