My dad is going to jail how do i cope?

My dad is going to jail and could be gone for a very long time! I dont want to have to get a shrink and I don't want to just mull around in my misfortunes. My friends haven't stopped asking me what is wrong ever since one of them saw the cops pull up to my house. I told him not to tell and he didn't but some of mmy other friends found out. Should I tell them
