I only speak for myself here, but to a certain extent we all sort of care for you and do worry that all will be OK, even though we dont know who you are.
It is scary being away from home for the first time especially in a foreign country. Your family who calls about getting home is concerned for you.
When you go to colleges, they have programs like Peer Orientation and consultions , in which fellow students help you adjust to your new life. Seminaries and Yeshivas dont have this. I know many people who did not succeed at their first college and succeeded elsewhere so dont be gloom because it didnt work out.
When I was a senior in High School we were pressured to go to Israel for a year, I did not want to go, I knew I wasnt ready to go away (I went to a local Secular college instead). It would have been the wrong decision for me at the time, even looking back at it now even though I am sorry I did not spend more time there
