How to get over somebody?

I went to girls camp for 5 days and I had to leave all my friends. I got so close to to the parents at camp because I didn't feel good so they helped me through a bad headache. Today I feel like I just lost one hole part of my family because that was what I was tought growing up. At camp everybody was my religion and I was told people in our church is like family. I get to see a few of the grown ups every Sunday but that feels so far away even if it is tomorrow. And I don't no if I will ever see the other parents and my other friends again.
