you said your injury occured in 2006 and you dont qualify for s/s disability? did you apply and were rejected or have you yet to appeal. obviously your injury influences your home life, what about your ability to maintain employment. do you have at least a year of full time employment history? if you meet the qualifications, have the physician evidence to support your claim, someone from home who would be willing to say yeah her injury has messed with our lives, then i would say apply. if you have been rejected previously i would find a lawyer in your are who works on a winning percentage scale so you don't have to hand over money you dont have. most of the good s/s disability lawyers have a conseltation period where they look over your case to see if it has potential, and it gives you the opportunity to see if you feel comfortable that they will represent you as you need,
good luck
it took me almost 3 years of no income to get s/s disability coverage
