How to cope with my boyfriend being grounded?

So my boyfriend has been grounded for four days now and the earliest his grounding will end is the 19th. I'm going absolutely crazy not being able to talk to him. How do I get over this and just patiently wait. Also is it bad that I am really pissed off at him for getting in trouble.

Finals are coming up so I can't really go out at all.
