Brain tumor concerns

F18, 5’8, 160 lbs, current meds: omepraxole, not a smoker. Hi i noticed a few days ago i started seeing black flashing in vision and tingling in my arms and legs. I have really bad health anxiety so when i looked up my symptoms and google said it could be a brain tumor i freaked out. I have been worried ever since. I am calling my eye doctor today. I was prescribed prozac recently and only took it for two days but the side effects were so bad that i stopped. So i haven't taken it for 3 days and im still getting these symptoms. Could this be related to the medication? | have no history of brain issues. I had a brain mri in March of 2023 due to issues with my menstrual cycle and everything came back clear. What are the chances this could be a brain tumor?
