Anyone on medicine for anxiety

I went to a neurologist and they said my headaches all anxiety and stress. I didn’t want to get a medication yet. But currently am in so much pain. Can anyone tell me names of medicines they have tried, whether they work and any side effects. It’s my last semester of senior year and I am overloaded trying to make graduation requirements so I’m stressed to the max! I wouldn’t take it everyday just when I know I will be stressed. The first week has been a lot for me.
