I had extreme anxiety when I lived in a big house--it has calmed down when we moved into an apartment that was smaller. How big is your apartment? Do you live alone? Do you have any pets? My main problems in the big house was I was super paranoid that spirits were watching me and when it was dark, I wouldn't leave my room, even if I had to go to the bathroom cause I was convinced there was something in the dark or someone broke in and was going to kill me. If I did manage to talk myself into leaving my room in the middle of the night, I would sprint to my destination and double check the locks. It has calmed down now, but I have a big fear of leaving my apartment and if I am alone, I don't feel inclined to leave my room unless my dog is with me.
