I was recently given pills for anxiety/depression, but I have an appointment for an MRI and I’m worried it might be something worse. Are these all common for someone with anxiety?

-face twitches around my mouth and in my left foot. Started a couple months before I started getting the other symptoms, but worsened
-vision blurriness, comes and goes
-mental fog/trouble concentrating
-fatigue
-severe anxiety, primarily regarding my health
-vertigo/lightheaded. Feels like I’m slightly drunk 24/7
-left arm goes numb
-issues with speech; hard to say what I’m thinking or think of the right words, often times I stutter or slur when I try speaking.

Thanks to anyone who can provide some clarity because I’m in a constant state of stress right now worrying about what I might have
