That’s a shame. It does sound from what you are saying as though your eyes might be the root cause, but you obviously need a professional to confirm that, not me! I’m surprised that you say that you aren’t good in verbal situations, but your written posts are extremely articulate and easy to understand, so might it be an idea to write down your challenges and hand it to the optometrist? Depending on your age, your eyesight can change significantly in 18 months. As I say, if you can’t get a satisfactory response from an optometrist I would see your GP as it’s obviously having a big impact on your life and there will be a solution somewhere. I wish you well with it.
