Dear Shy Girl,
Sorry to hear about your problems, unfortunately this isn't something I can help with. However, I did want to reply to the posts here and have deliberated at some length as to whether I should or not, so I hope you don't mind me putting my pennyworth in anyway?
There are a lot of us having to deal with the serious or not so serious consequences of illness, but to be fair you didn't actually mention you had eye disease and it did read as a general enquiry - much as I generally enquired about this topic when I first joined.
There are a lot of people here who will read posts and hope to find people helping each other in good spirit. Personally I'm battling diabetes and a close bereavement and I look to this site for inspiration, not words of war.
What I simply wanted to say (in a waffly way) is that fighting back at people trying to help won't help anyone, even if you don't agree with what they say.
I do hope you do get some answers that help you.
Griffy.
