Advice Needed!!!

A few years back my parents deeded their house to me. Shortly after, I created a “Deed of Conveyance” stating that I the Grantor give my mother the grantee “Life Estate” with the remainder to the Grantor/Me. Now, here’s the issue. My Mother is terminally ill and may die very soon. I have no clue of the process that needs to be taken upon my mother’s death in order to seize the house. I have disgruntled family members who will do anything possible to see that I don’t get the house. I would assume that there’s nothing they can do because it is clearly stated in the deed of conveyance that the remainder/house fall back to me. So, can anyone help me with the steps that need to be taken upon my mother’s death? Also, my mother is no longer living in the house and I fear that the house is being neglected and I was wondering if I have any rights to enter the premises to ensure upkeep. Lastly, all my mothers’ possessions are in the house and I know that if I don’t change the locks as soon as I can seize the property that my family will enter and take/destroy anything they can and say that that’s the state of the house when I received it. Please point me in the right direction.


Note: I did not myself create the "Deed of Conveyance". It was drawn up by a family Lawyer. It is an official document filed at the court house.

The following is an excerpt from the deed:

WITNESSETH:
That for and in consideration of One Dollar ($1.00) and love and affection, the receipt of which is hereby acknowledged by the Grantor (ME), the GRANTOR hereby bargains, sells, grants and convey unto the GRANTEE (MOTHER), a Life Estate with a remainder to the Grantor, the following described tract or parcel of land lying and being in BLANK COUNTY, BLANK STATE and more particularly described as follows:

DESCRIPTION OF LAND (OMITED FOR PRIVACY)

TO HAVE AND TO HOLD all of the above described property together with
all the rights, privileges, appurtenances, and improvements thereunto belonging unto the GRANTEE, during her lifetime with a remainder to the Grantor. When this says "together" does this mean that I have all the rights she does even while she has life estate?
