How do I get disabity

"How," depends on where you live and the reason you are unable to work. With no more information, that's about all the answer we can provide.

Well to me the obvious answer is to start by going to your local Social Security office. You can also apply on line. This is assuming that you are a U.S. citizen. The reason why doesn't matter. They will ask you all the questions and determine whether you are qualified no matter what your claiming your disability to be. This can take time. It's not something that you get overnight. It can take years if you have to appeal and you may have to even go to court.
