If you only intend to practice in the lower courts, then there isn't any problem. But, the distance between the lawyers and the judge in the High courts/Supreme court is more as compared to the judge and lawyers in the city courts. I don't think reading should be a problem as you can read from a judgment and then argue your case before the judge. One thing that does concern me is your difficulty to understand facial expressions and gestures of people because that carries a lot of weight. I'm stressing on its importance because when you're cross examining your opponent's witness/client, you have to read their facial expressions... Hm.. maybe that shouldn't be a problem either because the distance between the witness and the lawyer isn't that much either. I think you should visit the courts again and witness a cross examination in order to properly decide.

Why don't you switch to the teaching profession?
