Enjoy your freshman year. Enjoy every minute of it because these next 4/5 years are going to be the best time of your life. I am 2 years out of school already and I miss it like hell. Don't worry about the high school drama that will still linger into your freshman year at your college...it will pass soon enough.
Your parents will more than likely be there when you move into your dorm and they will want to help you with everything. Let them....they care. They want to help you move into this place because their baby is growing up and moving away. They can't hold on to you anymore and help you when you are hurt. They will call a million times the first year asking how things are going, answer them whenever you possibly can. They love you.
You will be confused, overwhelmed, excited, nervous, happy, sad, homesick, and you will feel hopeless at some times. That is perfectly normal. You're going to experience new things, new people, and have to make decisions for yourself now when only 4 months ago you had to raise your hand to go number two. Every campus has people readily available for you to go to if you feel overwhelmed and they can and will be glad to help you. Again, people love you and at this place it's not just your families.
You are going to make some great friends; cherish them. Do not forget your friends from high school, but when you start to realize that you are not so close to some of your high school friends as you used to be and you start to do more things with your college friends-- that's alright and it's perfectly normal. These friends you meet in college are going to enlighten and love you on a whole other level than your high school friends ever could. Love both set of friends equally.
Take elective classes that you will love, and it's alright to drop a class if it does not meet your expectations. I dropped a class solely based on the instructor when I attended Thiel College and I retook the class when a different, and in my opinion more better, professor offered the class. Just because a certain professor is the department head of your major or minor, does not mean they are the most fit to teach.
You have to remember a lot of these professors and doctors have been with the school for awhile and they are either getting older or more comfortable in their position. They may be a college professor, but they are still human and every human has a slaking point. My professor incident talked about his home country (Canada) way too much, and I never learned a thing from him. It's alright, it's your education and you have a say in what you learn.
Get involved...but not too involved. I know, every says "Get involved with everything" or " join all the clubs." I'm telling you no, don't do that. You will get overwhelmed more than you already are. Just join the clubs that interest you and make you feel wanted. No need to join everything just to meet people for the sake of meeting people.
The freshman 15 (yes as in weight gain) IS A THING! So is the sophomore 20...eat healthy and exercise regularly and you will be fine. Pizza is good in moderation...but don't have it every time the cafeteria offers it. Wraps are a godsend and so is the salad bar, get creative with your food.
Ladies, that cute boy over there you barely know who's smiling at you at the frat party you're at....yeah, don't sleep with him tonight. Guys, keep it in your pants. Don't do the drunk first week hookup and please actually know your lovers last name before you sleep with them. I won't go into details... just please trust me. You'll thank me later...
Speaking of parties...yes, carry your drink with you everywhere. No don't let that guy go off and get you a drink. GO WITH HIM! Men, you do the same. I was a bartender for frat parties and at clubs privately at schools. I've seen both men and women put stuff into drinks. Watch your shit, keep it in sight or in hand always.
So, as I conclude my ramble and rant while crying from memories of my freshman year...all I have to say is, have fun, stay safe, and make good choices.
