Who can represent me against my sisters who live in Minnesota?

You have rights in relation to your mother, seeing her and maybe moving her, but you have to take action.  Sounds like your mother is probably in need of a guardianship.  Because your mother is in Minnesota, you will have to hire an attorney in Minnesota; a Texas attorney cannot help you, unless that person is also licensed in Minnesota.  The laws in each start are different and, in some cases, can be vastly different, so it does not serve you to get advice regarding Texas law for a Minnesota guardianship issue.  My advice is to search for a Minnesota attorney as soon as possible. Sincerely, Kevin Spencer www.spencerlawpc.com P.S. - It looks like you have two other question posts regarding the same issue, so my advice would be the same for those as well.
