If she is upset and it is normal for her to contact you in the morning, it may not be because of your emotional distress. I think you should ask her, "What do you mean by what you wrote on qq today?" It makes her feel that you care about her. Then if she says it's nothing, you have to understand that don't ask again, because the more you ask her, the more annoying and meaningless it is. If she complains to you, you should listen, echo a word or two from time to time, don't talk back to her, then comfort her casually, cuddle her to make her happy and let her forget her troubles for the time being.
