How to cope with my anxiety for the next few weeks?

My boyfriend is busy studying for 2 very important tests that are 2 weeks away. In the meantime, I'm trying to control my anxiety and emotions. I miss him terribly. He's drastically reduced texting and other communication to the point of nonexistent the past week. Normally, I'd be thinking a relationship is about to end but logically I keep trying to remind myself, he's studying and his dad is probably breathing down his back too... his exams happen in 12 days.

How do I keep calm and composed? Is it better to give him space? Should I still text happy/positive things; even though he doesn't say much back? Even when I've flirted with him. How do I fight the feelings that he lost interest or doesn't love me; even though I KNOW he's just cramming mad?
