Pathways (www.gopathways.org) is excellent for what you're describing. It is a life-management program designed to help folks like your relative "who cannot seem to get back on her feet." Check it out on the web. It's based in Dallas. Although it is not "in-house," it is a 4-month long program where participants learn to live from the heart, deal with the past hurts, and, eventually, even make their own "life plans." Particiants check into a hotel for each segment of the program A same-gender roommate from the same class is assingned to hold down the costs. I recommend this even if your relative ends up living with you or not.
The 1st session, called "the Weekend," meets for Friday evening, Saturday (all day), and ends on Sunday.
The 2nd session called, "The WALK," is an intensive, Wed-Sun. There are usually 10 days between "the Weekend" and "the WALK.
The 3rd session called, "P-1" gives tools for dealing with life-issues. This meets the next month for one weekend, Friday-Sunday.
The 4th session called "P-2" gives even more tools dealing with life-issues. This also meets the next month for one weekend Friday-Sunday.
The 5th session called, "P-3" the next month's weekend session is much like icing on the cake, where graduation follows and graduates (who now have life-plans) stand up before the audience and proclaim in descriptive terms who they are!
