I’m sorry to hear you feel this way, it’s an awful nervous feeling. But, it’s normal. I felt the same way (YEARS ago) and my son just left yesterday for his freshman year and he is a bit the same way. One thing I noticed in your post, you seem to take a lot of guilt for things you shouldn’t. We all love our friends, but it’s YOUR time to fly. Your friend will be just fine. And you said it yourself that the dance girls become close. That will be great for you. Your friend will always be there for you, but moving forward is part of life! I’m sad that my son is 4 hours away but it is HIS time to fly so I have learned to accept that. Your mom will too, I am sure! Enjoy your weekend home!
