How do i overcome the fear and sadness of leaving my house to go to hostel for medical college?

As the topic says. I have been at my house with my mom dad since childhood all these 18 years never left them even for a month. Many of my friends are happy to go to hostels (other branch students) as they had family problems with parents, but in my case my family was the best according to me.

I am leaving this Saturday and i am super scared and nervous on how i will manage new surroundings as well as completely new education which i have never done before.

I have never felt so scared and emotional throughout my entire life. Please help , what can i do to make myself feel .

Thankyou!
