Ooops....I just yelled at my husband......?

He is working about 3 hours away from home and has been gone now for a week, but will be home next week. I love it when he calls and texts me, but I am sick and have had very little sleep in the last 4 days. This morning he has already texted me 45 times. That's no lie. I feel like a slave to this damn cell phone. I can't even try to get some rest cause he is constantly texting me over nothing. If I don't answer him fast enough, then he calls the home phone. So last time he called I got a little ticked off and told him I was tired and wanted some rest, now he thinks I'm mad at him. What's the best way to handle this?
