You do have a chance. There is good advice above. Start calling law firms, and call at least 4. Compare what they say. The main thing that would be against you is that you are probably relatively young. The younger you are the more they figure that you can eventually find a way to adapt to your disability. The best thing you have going for you is that you do have a paper trail of being treated.

Some law firms will tell you to apply on your own and come back to them, if you get denied. I don't recommend that to anyone. If you can not find a law firm to take you on right from the get-go, that means that they don't see you as having that good of a case. They tend to be right in their predictions.
