2. I'm worried about homesickness.
I won't lie: Homesickness is real and it's not easy.
Living in the different environment may cause the ups and downs feelings. Homesickness is the basic thing that easy to happen when you are fear of something. This indicates that all you need to do is overcome a fear. What are you really afraid of? We need to ask ourselves why are we doing what we are doing? What is the benefit we will get if we don't give up and moving on? Find the real reason and try to think at the positive way. You might live in the different place but you are not alone! Talk about how you feel with your friends who are experiencing it too and remember that now is 2017, it's so easy to keep in touch with everyone back home by using social media.
Another way to help you get rid of the homesick feeling is to have no time to think about it. For me, I like to create activities to challenge myself everyday. Make plans and set goals to achieve it. The goals might be in short or long term depend on you but know that it's good for you and society. Example: On Monday, I will introduce myself to 5 strangers, On Tuesday, I will take up a new interesting hobby with friends. On Wednesday to Friday, I will start learning other languages, etc.
See! There are lots of activities you can do to help you get rid of homesick feeling and even more you can make new friends. If you know how to deal with your feelings, you'll feel free to explore an exciting new world!
