I also had this experience when I had to leave my house and family. It had happened when I was 18 yeas old. I do remember those day, my dad called me and said that I would learn the world more and the most important thing was I had to know my goal and shouldnt up set when I had got troubles.
The same as I would like to tell you. We have to learn life and tgis world. We leave the house and family for our future. It is not a sad story, it is a great opportunity for you to grow up. You have to be smart and careful when you make any decisions. Keep in mind that there are both good and bad like 2 slides of cone. The most important thing is positive thinking when you get trouble and negative ideas can be used as a defense mechanism to protect the bad event you will face.
