What is happening to me?

So this started happening 2 months ago. everyday I feel like im shaking and i feel very weak. I also get 2 second toothaches like every half hour each day. I have been taking pain relievers for 2 weeks now and nothings working. I also have tantrums in my sleep. i will scream, roll out of bed, tear up my room, and i will start breaking things for some reason. idk if their is something wrong with my brain. but this is really worrying me and I have checked up with a nurse and she didnt have an idea what to do. ): PLEASEEEEEE HELP btw im only 16
