For me the most obvious way is that I feel more limited with my time, it's simply not as easy to take a student out of the classroom even for 15 minutes.
Additionally, I think counselors have been doing "Common Core" for a long time. I could be wrong, but I feel like Common Core is a push towards independent learning and problem solving. Well don't we do that every day? (I won't tell you how to fix this problem with your friend, but I can help you pick and practice an option that works best for you. I can't fix what's happening at home, but I can help you develop coping skills.)
For me the best way to reach my older students, meet Common Core standards, and to really see growth in how my students treat each other is through Socratic Seminars.
I can't encourage enough you to use Socractic Seminars with your students (grades 5 up). Imagine running a small group, but reaching triple the amount of students. Imagine creating a positive classroom environment, tackling bullying, practicing social skills, and encouraging higher order thinking skills in 45 minutes. It's great, but the beginning stages can be frustrating so here are my helpful tips:

It's going to practice:
Socratic seminars take a certain flow and self control. We are asking a lot of our students (and even ourselves). They have to hold their thoughts/opinions until we have asked for them, they must practice discussing not debating, they can't have side conversations, we can't jump in a save them! Seminars bring up uncomfortable feelings, and they need to practice coping with those. For example, at the end of my last seminar I got feedback from several students that they just didn't like it. When I looked closer at the students that said they didn't care for this lesson I realized they fell into one (or both) of two categories: they had stated opinions that differed from the majority and/or they were students that loved concrete answers (they were uncomfortable in the gray they wanted 1+1=2 always). Practice, practice, practice.
