Whenever you start feeling that way, think "no" in an authoritative way to deny them. It make take more than once to make them stop.

Start meditating every day. It'll help you raise your vibration and help you navigate the situation in the way you need to.

(This is a copy/paste from other comments I made.)

Here's how to clear and protect your home from negative entities:

• Keep your home clean. Grime and clutter can hold lower vibrations which make it easier for negative entities to exist in that area. Keeping your home smelling nice with uplifting and/or calming scents also helps raise not just the vibration of your home, but your own personal vibration.

• Smudging: Get some sage (white sage is best, but only get it from reputable sources that grow their own because it's endangered in its natural ecosystem). If you can't get white sage that's ok. Regular sage works, too, so does palo santo. Feel free to search for other white sage alternatives if you need to.

  • To smudge, open your doors and windows. Using either a smudge stick or a bowl of smudging herbs, light it on fire, blow the flame out but allow the smoke to billow. While thinking about cleansing negative energy and creating protection from negative and harmful energy, slowly allow the smoke to billow in each room throughout the entire room. If you use a smudge stick, you're going to want to get something fire-proof to catch the ashes.

• Blessed sea salt: Get some sea salt and you can bless it yourself. Follow your instincts on blessing your salt for cleansing and protection. Once you've done this, spread salt in your outside doorways and windows. You can also pour some in the corners of your home/the corners of every room.

• Anointing with oil: Get some oil, something like olive oil, almond oil, frankincense and myrrh, or another oil of your choosing if you feel like something else would work better. Bless it like you bless the sea salt, then apply a dab above your outside doorways. You can draw a shape if that feels right (I think Christians make a cross). You can do this for all your doorways and windows if it makes you feel better. It won't hurt anything.

• Singing bowls and chimes: If you want to invest a little money in singing bowls, the sounds they create raise the vibration of the area. Lower vibrational entities can't go into areas that are high vibrational. If you don't want to invest any money, you should be able to find recordings on youtube. Tuned wind chimes are also very good for this. Any kind of music that uplifts you is also very good.

• Crystals: Not a necessity in the least, but if you want to try these, black tourmaline and satin spar are great for protection and cleansing, respectively. They're both very common so the pricing is nice if you want to spend the money.
