When People Constantly Text Me

I was texting my friend one night and I was getting tired so I told her if I didn’t text her back I fell asleep. So I fell asleep and she sent me a text. I didn’t answer and she kept asking if I was there. Then in the morning she texted me at 6:30. Seriously? She knows I never wake up at 6:30 in the summer. Then when I didn’t answer she sent me four more texts. When I woke up I had ten texts all from her. And if don’t have my phone for half an hour and I don’t answer her she’ll freak out and send me seven more texts sometimes. It’s so annoying! Please stop texting me asking if I’m there, I’m obviously not.
