Sudden panic attack. Light sensitivity tinitus unable to drive. Allergy tablets sideeffects.

My story begins in December 2025 when I suddenly had a panic attack while driving. After that night, I started experiencing sudden vision changes. Everything became blurred, and I developed brain fog, tinnitus in both ears and sensitivity to light and loud noises. It has been six months since then, and I am still dealing with the same anxiety. I am unable to drive because of the high anxiety. I am wondering how long this anxiety can stay in my body.

I never had anxiety in my life. It just appeared out of nowhere one night. I have been taking allergy tablets (fexofenadine 180mg) for hay fever for the last three years. I think the anxiety might have come as a side effect of those allergy tablets. It has been six months now, and my anxiety is not going away even though I have stopped taking those tablets since my first panic attack.

Has anyone else experienced the same symptoms? If so, please let me know how you managed to get rid of your anxiety.

It is causing me tinnitus, light sensitivity and anxiety is causing my face to tingling sensation and driving panic attacks.
