Under normal circumstances I'd say yes, but I see a potential problem.
While I have no specific information about Mississippi, in most if not all states you must have worked x number of weeks or earned y number of dollars in the past year to fifteen months before you can collect. If you have been out on disabilty for a year, it's likely that you have not met the minimum requirements to collect at this time.
It is certainly worth a try, but under the situation you describe, I cannot give you the unqualified yes that I would give if your leave were of a shorter duration.
