Yes,extremely tough to adjust to a new place, even for studying elsewhere e for 10 years, I still find it tough to adjust to new environment. You are thrilled to start a new life, but still insanely miss friends and family.
My solution to this problem is :
First,constantly tell yourself this is normal,do not have pressures and choke yourself.
Second,contact your friends and family to exchange your feelings and let them know you miss and care about them. Their love and support will cure you from desperate.
Third, hanging out with others and try to have something fun in your life. You have to remember that you are away from your home for a reason, and creating a happy life is very first crucial part of it.
Wish you find my answer helpful,please let me know you have other questions.
