DH and I had a Sr. last year and I'll take this from a different perspective. These kids have had the same routine for the past 13 years with school. Get up, go to school, talk with friends, do homework, do activity, go to bed, repeat. Fast forward to Jr. and Sr. year....What do you want to do for the rest of your life? Where do you want to go to school? Those scores aren't going to cut it. Are you applying? Where? That's too expensive. Did you apply for scholarships? How many? How do you expect to pay for that? Where are you going to live? You're an adult now..... On top of that, parents often feel as though they haven't prepared them well enough and start giving crash courses in life skills.
With Sr's, my best advice is talk and listen. If they are shutting down, more than likely life is feeling intense. If they are partying all the time, they are probably feeling like they will never have fun again. If they are giving up, they may be lacking hope. Remind these girls cheer is what is familiar, can be the soft place to land and be a great outlet when things are stressful. Even though they're entitled, they may have some pretty intense expectations looming over their heads. Making plans to leave everything you love and all that is familiar behind is pretty overwhelming.
I all of the sudden have the urge to watch St. Elmo's Fire:D
