I have really bad anxiety and today is my first day of senior year. I was fine up until 3 days ago when I got an AWFUL toothache and it hasn't went away since and I barely slept last night because it hurt so bad, and I was worrying so much about missing the first day or missing classes that I made myself feel sick. Now I have an awful toothache AND I feel like I'm going to throw up. Painkillers don't help and I can't go to the dentist because I can't miss class. Help?? I'm freaking out, this isn't how I envisioned my senior year would start, I'm in so much pain and feel so sick that I feel super irritated and don't even want to leave the house
