To specify my blindness

The tumor that took my vision, did so, by smashing and thus killing my optical nerves. So that means that if you look at me, my eyes appear fine (as they are) so I have to make a really quick decision as to how I want to deal with who ever it is I am talking to…….do I want to try to nutshell the fact that I was blinded by a HUGE brain tumor and tell them that I can’t see real well OR just act as though I am fine (even though I am clearly not ok) So when people see me texting or writing an email they think “he’s not blind!” but I am fucking blind and the only reason I can text or email is really simple……WHITE LETTERS ON A BLACK BACKGROUND!! It sounds stupid but it is the reality of my hell on earth. I used to be so independent but I have been reduced to what amounts to a child and it fuckin blows, as if I needed ANOTHER reason to want to just end it. EVERYTHING that we use our vision to do is unbeleivably hard now and I do mean EVERYTHING!
