This happens to me all the time. I get migraines and this sounds like that or a tension headache. Have you ever been evaluated for either before? A few good tests to do at home to determine stroke or serious neuro issues - close your eyes and hold out your arms in front of you, if they're balanced when you open your eyes that's a good sign nothing major is wrong, check if your smile is even, your pupils are even and reactive to light, move all fingers and toes, and have someone else listen to your speech for slurring. All things I have learned to help cope with symptoms and anxiety.
