First off let me say that of course, your situation is horrible and I wouldn't wish that upon anyone but we also have to be realistic when it comes to this situation and face the fact that a game that would be very challenging but doable for a person with a disability as severe as yours, is probably too easy for someone without a disability and as such not entertaining which would severely hurt the makers. Therefor, I wouldn't want ANet to oblige here. That being said, I am sure there are plenty of people out there who are more than willing to help you, including myself :) I am more than happy to be a Teleport To Friend target or help you with a portal to where you need to be or with questing otherwise :)
