How to cope up with tears ?

S • not TTC

I came here for higher studies (coaching) . I'm 18, and dad and I came here to admit me.

Now that I live in a hostel and he is living in the guest room, I'm home sick. The very thought that he'll be leaving in an hour is making me worse.

I don't want to cry in front of him. What do I do to stop crying in front of him?

Am I being sensible and normal ?

P.s- I didn't make friend here because girls here hardly talk to each other, its cut throat competition in here.
