Your best move is to go to court and become a managing conservator with the right to designate their primary residence. You can find the petition and the order in Suit Affecting the Parent Child Relationship at a law library. After you file the petition, you will need to serve your mother and the father/s of your siblings. You should include a request that the child support be redirected to you 9this may be the thing that causes your mother to fight it).

While I agree with Ms. Lowry, it could get messy real quick because of the child support and SSI. I suggest that you consult with an attorney with experience in guardianships. Even if successful in getting appointed their guardian results in annual reporting issues on how you spent the SSI to the Court. See a lawyer.
My response herein is an attempt to give you general information and direction and is not intended to constitute an attorney-client relationship as perceived by state law.
You don't want guardianship, you want custody which is handled in the family court system. Guardianship is a probate matter handled in a different group of courts in Harris County.
I recommend that you hire an experienced family law attorney to help you. As you can see from the other 2 attorneys that have answered, it is a complex matter. If both parents don't sign the paperwork approving the change, then they need to be served with legal paperwork. It's not that easy for you to get them served properly.
