Understand this is a normal feeling
Like I said at the beginning of this post, this is a normal feeling to have. It's important to know that you are not alone in feeling this way. Most of us experience homesickness at some point in college. The degree varies from person to person, but I'm willing to bet more people share these feelings than you'd think. Learning to acknowledge and accept your homesickness is helpful in dealing with it.
Get used to new surroundings
The more comfortable you get with your new campus and the surrounding area, the better off you will be. Take some time to walk around campus, find some places you like to eat, discover a great study spot, and figure out things you like to do there.
Create your own space- a home away from home
Make your room a place you feel safe and relaxed in. This is your home away from home, so it actually needs to feel like it. I recommend decorating it and adding items that make it feel happy to you. For me, I liked to have pictures and quotes hanging up. Additionally, having a clean and organized space was helpful.
Stay connected- but not too connected
Talk to other people on campus
Sharing with your friends how you feel might help you deal with overcoming this. They will be able to support you and force you out of your comfort zone a little bit. If you don't tell them, then they might wonder why you are being so distant. You also could consider talking to your advisor or the campus counselor.
Make time for sadness but not too much time
It's okay to be sad sometimes, but it's definitely not okay to allow yourself to be in a constant state of sadness. Letting your feelings out every once in awhile is good because it prevents you from bottling everything up inside. Sometimes you might actually feel better after letting it all out. Being sad all the time will prevent you from being happy as well as create a pessimistic outlook on college.
Getting involved on campus and the community will definitely help make things better. Take some time to look at the clubs your campus has to offer. Attend a few meetings to see if these clubs are a good fit for you. This will help you meet more people and become busier. When you are busier, you have less time to dwell on missing home.
Last but not least, try to stay positive. This won't alway be easy, but it will help you get through things much easier. Sometimes in life we have to fake it until we make it. If you are able to convince yourself that you are happy, then it might just work.
Best of luck!
