I can't cope with anxiety, help

I asked a question in mail.ru answers about narrowing of vision, there were 9 answers, I came across one person who said that I need to go to an ophthalmologist, he wrote so cleverly and in long text he had a cookie on his avatar, I wrote to him that the ophthalmologist did not find any problems with vision, what if the MRI does not help? He sent me an answer, I wanted to read it, but the question was deleted, a message appeared that there is no more answer, now when I sleep my heart beats hard, adrenaline and rapid breathing do not give me peace, suddenly there was something important in that question, I want to see this answer as soon as possible, what should I do? How to unblock the question and read that answer?
