It is possible to "outgrow" your friends. Pinkbutterfly has a good point, you are ready to start that next chapter of your life. Perhaps your friends are not ready to let go of this chapter quite yet. That's okay, everyone grows and progresses differently. Seems like you are more motivated and passionate and that's a good thing. Loving your career will give you a competitive edge because that stuff shows through your work and dedication. It's just a little bump in the road. Maybe looking forward to graduation and practicing guided imagery can help? Envision how good you will feel once you are done and beginning to look for a job or internship. I'm sure once you begin putting your degree to use, you will make new friends who are on the same level as you. Hang in there.
