It is often hard to tell someone what you need without feeling like you are complaining, but in order to get the right accommodation whether it is a special chair, a phone, a ramp or some technology it is important to speak-up. Identify the need in writing, and provide facts and data. It is often how you communicate the need that will successfully grant you the accommodation. Sometime speaking out will also help others. Before speaking out, I would advice getting an advocate to help facilitate the need. Even in today's world having a disability is still hard to balance the communication as the unfortunate some abuse the process and hurt the rest of us.
