How Is a House Purified?

Hello, honored rabbi,

We moved into a new house two months ago, one that people had lived in before us. We renovated and arranged it, and everything is nice and beautiful; we even removed the television from the house entirely. We put a Torah bookshelf in the living room, there are holy pictures, and there are new mezuzot, and still my feeling has not been good since the move. I feel that it is difficult for me in the house, heavy energies, it is harder for me with the children and with my husband, and there is more tension and distance between us. True, we went through a busy period, and I am sure that it affected everything, and yet I thought that maybe there may be a connection to the house itself. In your opinion, do I need to do some kind of purification for the house... and how?

Thank you in advance!
