Yes, it is SO ironic!!! I've had 1 daughter in Catholic hs, and 1 in public hs, so I can tell you that mean girls exist in both! While the daughter in Catholic school was more outspoken and could "hold her own" with the mean girls, she still ran into situations where she felt out of the loop. My public-school daughter is quieter, very nice, but felt rejected countless times, so much so that she gave up facebook because it hurt too much to see her "friends" having fun in pictures of parties she was not invited to. Thankfully, she sought advice from a close adult friend with experience in teenage issues, and she coped a lot better. She found a few friends that like her for who she is. She took up the guitar and voice lessons, and has become quite good in both. She focused on her schoolwork and did beautifully. And even though she couldn't get into a limo for the prom (the mean girls never thought to include her), she's going with a date and is thrilled to go, even if I have to take them there myself. She is looking forward to graduation, college, and the friends she hopes to make there. I feel quite certain that she will, she is sociable and a true friend. The immaturity that exists in hs disappears over time as they go through college, but for now, I would suggest that your daughter look around for another kind, quiet soul to become friends with. They could end up being best friends for life! Also a hobby, like my daughter did with guitar, is great for her self esteem. I feel for both of you, I have gone through it twice now, but I promise, it gets better, and she will be stronger for it, and you and your daughter will bond even tighter.
