Well first off, we have all been there. Even if some people don't want to admit it, we were all once the frightened incoming freshman. New school, new people and sometimes even a new state to throw a curveball into the once certain and stable life we called "high school." For most of you, you will not be embarking on the college journey with any of the people you knew from home nor your friends you are so comfortable with. And that is okay. I promise.
Now you may be freaking out to live on your own and make that big adjustment but I am telling you right now, you will adjust a lot faster than you think. Even if it is a completely new state and environment, in due time you will find your niche within the school you have chosen as well as a group of friends to back you up always. Most people say that you don't really stay close with your high school friends and sometimes may never talk to some of them ever again. Now I did not believe this at first, but it could not be more true. Even if you have falling outs with friends, it may be totally heartbreaking in the moment but the true friends will stay and sometimes you just outgrow people, that is life. But soon enough (may not be the first day, but soon after you start college) you will find your friends, and they will be better than anyone you've ever met before college.
In the beginning you may feel horribly homesick, but once classes start up, you establish your friends and get involved on campus, you will be too busy to be upset. Home is where the heart is don't get me, wrong but you will quickly realize that home will always be home, no matter what. Your family will always be there to comfort you with open arms no matter how far away they are, through the good and bad times. They are also only a phone call away so never hesitate to call! (Make sure to call your family often, they miss you just as much as you miss them, if not more!)
If you are worried about the college work load I am not hear to lie to you, it is way harder than high school. Not even to exaggerate, high school was a BREEZE compared to college (even AP's). So with this being said, make sure you stay on top of your work from the start. I'm not saying this to scare you but you make you aware that you cannot treat college courses as high school classes or life will hit you, and it will hit you hard.
In the end college is an amazing experience and something that will really help prepare you for the real world. Don't be too nervous because I promise you will adjust quickly and find your place much sooner than later. Have fun, stay safe & good luck! :)
