I cried most of my first year every time my mom dropped me off. I went home every weekend. Then I realized it's harder when you go home, so I started staying a little bit more until I was able to stay and go. Now that I'm a junior, I stay on campus more.

And what is while is I would go on camping trips for months and stay with my grandma
