Why does my brain glitch?

[Kayla01234]

How I originally explained it was it's like having bad wifi while streaming a movie... perfect picture, glitch, glitch, picture freezes but can still hear sounds. I have to shut my eyes and wait for the pressure to release. Recently I've been explaining like trying to stare in the same direction as the sun... you feel your muscles straining to see while you blink uncontrollably. This started happening to me a couple years ago. I started taking Zoloft for anxiety. I avoided drinking alcohol and caffeine. The frequency of the occurrences reduced then went away entirely. After a year or so I decided to stop taking the medication. It's been about a year since then and it's started happening again. Its terrifying!! It's hard to function in daily life. It happens more frequently if I've watched a lot of tv, or am tired or hungry, or in social situations even just talking to one person, or in public. Anxiety medication has helped in the past but I really don't think I have anxiety. I do have additional new stressors in my life but I feel excited and good about them all. It's the glitches that hold me back. I'm a healthy 23 year old female.
