Hi When My Daughter Was 3 She Fell Off A

hi when my daughter was 3 she fell off a table and hit her head face first on ceramic tile. I went to her dr who confirmed she broker her nose but not much could be done about it. Fast forward a few years , she was having a lot of explosive behavior , anger outburst but only at home. She did very well at school , fats forward to 14 year old, she has been complaining for a few yrs that she was always stuffed up , bags under eyes, just recently went thru some depression which she is much better now. We always though she was allergic to milk and wheat so we eliminated some of that out of her diet. By looking at her , clearly her nose looks off. I do have a dr apt next week to get a referral to a nose specialist. Could the trauma to her nose devolped into her not breathing properly which effected her behavior also?
