There's probably a lot of people with similar feelings, especially in first year. \\Find people who like road trips and long talks and tv mornings when it snows.
Your old world isn't disappearing, it's just expanding. Just because somethings are different, doesn't mean everything has to change.

I'm sure you'll find people who want to make lifelong friendships too.

And if you really don't want to "grow up there is nothing to look forward to except for work, marriage, and eventually death" then you won't. You'll do something else that you like better. As they say : life is what you make of it.

That is tough. I can understand how you feel. I hope you do make it a point to stay in touch with people and not just on Facebook. Is there a reason you had to go away? What about going back and finding a life in your hometown without college? Any decent jobs there? An apprentice to someone in your town who makes a decent living? (Like a plumber or real estate person?) Or maybe start or buy a business? Is there a way you can go back and get some of your earlier life back?

Your life will be different, embrace it. Who knows, you may enjoy it.

I know hug
