Can my wife file with me as a dependent, if I am disabled but don't collect ssi yet?

I am adult disabled who does not collect ssi payments or any income from anywhere. I have been this way for at least four years, but my wife and I file jointly as we have always done. My wife is the only one who works, and makes a income. I was wondering if We should be filing different and if I can be a dependent under her tax return??? Please help,
