You aren't alone. Anxiety can make you feel sick, and unfortunately, I'm one of those that gets sick from anxiety, too.

There's a possibility that it is your medicine, but that doesn't mean that it is! Just as Jaymoq said, I encourage you to seek professional help with your anxiety, too.

Take some time to inspect your life and see if you did anything differently. Did you have a change or event occur in your life recently? Sometimes that can be the cause of anxiety. Pinpointing the root of your anxiety might take some time.

Good luck. I hope that you find the help that you need!
