Martial Arts for a Veteran

I am a veteran of Kosovo and 2 tours in Iraq. I have mental health issues with dealing with social situations my only outlet is in martial arts. I have lost my transportation due to emissions laws and live 50 miles from the city up in the mountains so a bus is not an option. I would like to get a small fuel efficiant car and pay for a year of Brazilian Ju Jitsu. I am currently in a class and would hate not to go it has helped me physically and mentally as well as giving me social interaction.
