Ground and shield yourself first thing in the morning and again before sleep. You might find it most useful to do her room as often and the house once a day. If you wish invite your guides and allies to help if they can. Send your grounding cord from your root chakra down through the earth star chakra (about 1' below your feet)and then on to the core of the earth. You can also send roots from your feet into the earth. I usually do both. Then send up your celestial cord from your crown chakra up to the transpersonal point into the higher realms. Breath in the light from the earth up into your body until it fountains out your crown chakra to flow back down into the earth. With the energy entering the crown breath it down into your body until it flows down your grounding cord into the earth. Thank the universe, the earth, and/or your higher power(s) of choice for these gifts and you are done.
A bit on the Earth Star Chakra here:

I do this after grounding and shielding so I am balanced and protected before I start. I look at myself using my mind's eye and check for cords. Usually I can't see them at first until I 'pretend' I can see them so my logical brain stops sabotauging the process. Then I can see cords between me and others. I look for the icky ones that look awful or I feel are draining me. I Either then gather all of them together, cut them, and then breathe light into the areas they hooked in until I have burned away any residue or I breath light into the areas where they hook in until they cords break off of themselves. Often I use purple light but any will work so choose the one that suits you best. Then I place bandages of gold mesh over those areas to shield them so they cords can't be reattached as the areas heal.
Cords can come from many lifetimes and sometimes are part of old agreements. Affriming that you release these cords and any old vows, agreements, contracts or anything of that sort that does not serve your highest good can help release these so they won't come back. I try different wordings to make sure I cover the bases especially when ending a bad relationship *and* when i need to reduce the emotional/mental stuff I pick up from someone I do wish to have a relationship with. Releasing old stuff is good. Often I have found I have kept hold of old stuff for many lifetimes hauling it along long after I could have let it go. Sometimes it is stuff I should never have picked up as it was somebody else's but did out of compassion only to see the person go through a similar horrible experience in yet another life. Whatever the source it is good to check periodically to see what can be cleared out of the old psychic storage facility.
