You need to contact an attorney in North Carolina to help you with the child support matter. They can file a motion to modify your support order now that you are on disability. As for the drivers license, I would contact the North Carolina DMV and find out from them what the want for the restoration of your driving privileges. Given how old the revocation is all you probably need to do is pay a restoration fee and take the driving test again.
You will need to clear your NC license before MA will let you get a license. Retain a NC attorney to help through the process.
