As for financial assistance, depending on your situation, there is a multitude of charities that offer assistance to those who could not afford such transportation. Moreover, if you have Medicaid, in some instances they may cover the cost of transportation. It is important to note that some states may require a co pay for the use of the service, and you may be limited in the number of trips to which you are entitled, but that also depends on the situation. If all else fails there is always an option to use a crowd funding site to raise the funds needed to secure your travel.
