I have moderate scoliosis with a 32 degree curve in two place's upon my spine. Can i qualify for ssi?

I cannot stand for more than a hour. I have sharp shooting pains that go from my spine to my hip's, shoulders, neck, knees and elbows. I cannot bend, stoop or do any vigorous activity. And I'm only 19, I would rather not get onto disability but I have to have a Income. I have a job I work Two hours a day twice a week cleaning a house, After i get home I go to sleep because I'm in so much pain I can barley stand. I don't know what to do. Please let me know what you think I should do. Thank you.
