Holy crap that's pretty grim.
Is it only your right eye? Any chance you could marry a Canadian?
My mom lost vision in the right eye couple years ago, when its optic nerve got squished by the growing tumours in her brain. We has low key been panicking about what happens when it squishes her remaining eye, but she had a stroke last week and so maybe she might not live for that to be an issue.
Sorry that was irrelevant. Just wanted to say, yeah sometimes stuff just sucks so bad.
I hope you find an affordable cure. That sounds so disgusting to even type.
