Sounds a lot like what I have had going on. The ringing in my ears is pretty quiet, though. But I never used to have a constant ringing. Not until I passed out. And I do have low blood pressure. Interestingly, I found out that my dad has had something similar for years. He had bad vertigo a few years ago, and he has had the same problem I do with moving too quickly or standing up to fast - dizzy, feeling like someone is going to cut your strings and you'll collapse, sick. The doctors don't know what it is that's causing it for him, either.
Some of my problem with my eyes is eyestrain, I think. Serious eyestrain. I've been using eye drops and trying to remember to blink more.
That chick is Vona, the little black Icelandic I lost. Cute little thing. I'm glad I got pictures of her and Sorg, the other chick that we lost.
Edit: I forgot to say, I'm also trying to adjust my diet and nutrition. I don't trust all of the medications that are floating around out there. I'd rather try fixing some things naturally before I get loaded up on other things. BUT, that is only my personal view
