I'm extremely anxious. I have an appointment in 30 minutes to get 2 cavities filled &amp; I'm so nervous. A week ago I went to the dentist for the first time in 4 years &amp; although they made me feel better, &amp; I didn't feel anxious at all before today, I woke up with severe anxiety about this. I know the needle getting me numb is going to hurt, &amp; I hate the sound of the drill. I wish I could go to sleep for it but that seems so unnecessary. I just need to get through this for the sake of my health but I'm so anxious.
