Seizures or anxiety


For the last 3 days, I have been having episodes of extreme dizziness, feeling faint, confusion, blurred vision and tiredness. I also have insomnia. I have been diagnosed with anxiety and depression and possible ADHD. I went to the doctors about this and they said that it was an anxiety attack. They did not happen over the weekend so that's why they don't think it could be anything but my anxiety. It started really rapidly, last Wednesday. Could it be anxiety or a small seizure?
