Everyone here has an opinion and will tell you about it. 
I recommend *demanding* what you need. If family member refuse to watch tv with closed captioning, tell them that you need it. If they still complain, quit watching tv with them and go do something else. When you refuse to hang around them while they are refusing to accommodate you, they will either change or lose your companionship.
You have to learn to advocate for yourself and you may not feel comfortable in this role at first. Let them call you a bitch. I say, that's Mrs. Bitch to you! :P
You will probably be forced to reevaluate certain relationships in your life, but that may be for the best. I've declined to keep up some relationships when I discovered that the people were not supportive. In my case, this included some family members, too.
Learn ASL and get involved in the deaf community. Not only is it essential for your mental health, it will enrich your life, too.
