Illusion disorder/perception problems.

I have path breaking problem here. The thing is that I am having a kind of metamorphosia from 2 months in which straight lines appear bent or slanted . Similarly rectanglelook more of a trapezoid. Symptoms are persistent 24/7.Its evident on computer screen, books all the time. I have had dilated retinal exams as well as macular OCT, and everything has come out normal as per opthalmologists. Now I want your advice. Is it neuropsychiatric issue? I have remained under hypochondria/health related anxiety since 2 years. I have issue of overthinking/restless mind. Even before this visual problem, my mind was disturbed and I felt I put too much strain on it. What would cure me in this situation? SSRI or its rather a case of antipsychotic medicine? I already have a prescription of low dose SSRI from an internist which I am about to start. But I want to know your views whether it is what will cure me of the problem. Have you encountered such case in clinical practice. What is it exactly?
