I had an anxiety attack yesterday, & after talking out my frustration, I felt much better. Later on, I had an unbearable headache, sore throat, & nausea.
Besides all the symptoms you had, I vomit. My nerves go so haywire that my stomach cannot take it. I end up getting sick to my stomach after the headache from the nerves, sore throat from yelling, and nausea from nerves.
