Please HELP

My 3 year old had a seizure Sunday night took her to the dr Monday and was told it was febrile. Flu test negative. From Monday til Thursday she had a fever over 100. 103 at the highest. Took her to the ER and was told she was flu positive and she has an ear infection. Shes still got a fever, shes cranky. Shes peeing but not as much (yes I told the er dr that) she sleeps constantly isn't up for more than an hour a day. She seems confused and doesn't want to talk, and when she does talk she talks mumbled and hard to understand. She has a blank stare quite a bit. Please tell me this is just due to the flu/ear infection. And how long will this last. I'm SOOO scared shes not ok. Please please please someone let me know something
