Ask questions by SMS

I have a friend who has been telling me that she is unhappy since I met her. Sometimes when I am eating or getting ready for bed, she will send me a message! QQ chat is all her mood! This makes me feel tired gradually! As a friend, of course I am willing to help her and listen to her, but every time she comes to discuss her life with me with a gray mood! Maybe your situation is similar to mine. If you ask too many questions, she will get angry. "If you really don't understand that much, ask the teacher!" Adjust it a little first, and don't send her so many messages!
