Homesickness

I have go back from Kampar since Thusday.
The first time I live in Kampar till Thusday I very miss my home, my family.
That time I am sure I gt homesick already. I can remember last Sunday when I first moved in there I cry in the night, I miss my home, I can't adapt the university life.
I know many peoples will laugh at me saying me is like a baby, always need to stay in the home but I have to admit that I am like a baby.
I still remember 1st time I go for study in primary school, I cry for a whole month, I know my adapt ability is very weak and I feel I very weak, can't handle with pressure, scare to make new friends, scare many things, easy become worry and anxious.
I very admire those who can adapt to new environment very fast and won't get homesick.
Now I really don't know what should I do. I know nobody can help me except myself.
I am 19 years old already but I still like a small child always need stick with home and parents.
I know I have to be independent but I don't know how.
