I have blurred vision, in both eyes.?

I went and saw an optometrist not to long ago, maybe a week ago at the most. He said everything was fine and my vision was excellent. But today today my vision started getting blurry. Also i was sorta sick yesterday but I'm recovering. I have a headache but its getting better from yesterday and i had a stomach ache too but its pretty much gone. Also I've been having hearing problems, ringing in my ears (not consistent at all and i only hear it at night if even and very weak) and yesterday i got the feeling a lot like when your on an airplane. I have sorta of an undiagnosed anxiety disorder too. I worry a lot about my health (as you probably noticed) and its always just nothing.
