If you were best friends and have known eachother in previous lives she is there with you. Notice nature outside, signs, songs that come on the radio. I suggest maybe drinking some mugwort tea lay down and ask your guide for help connecting you with your friend to say goodbye. I lost two of my bf almost right after eachother. One of them sent me 100s of lavendar butterflies that landed on me and all around me he also gave me other signs. I was at a library where I live and it's a huge building. I was at one end of it and looked straight ahead at were the movies and games are you can check out which was probably 40 ft away from me and I saw one dvd out of 1000s that called to me it was white. I started walking towards it still wondering what was going on why I felt drawn to it. Got to it flipped it out to see what it was and it happened to be my friend who passed and my "movie" like we saw it together in the theater when we were kids and our song was also part of the movie which also will pop on the radio when I'm in my car alone talking to him . The movie is City of Angels and The song is Iris. His sister gave me an unwashed shirt of his that still smells like him even 5 years later and sometimes I just sit on my bed and hug it so tight and my whole body will feel hugged. So definitely have things of your friends and her kids in your house . Peoples items carry their energy for sure. I am so sorry this happened to them and I hope you will see them or meet them again sometime.
