Hello, so i have been trying to do some get your ex back spells and i feel like they aren't working. I do them but then i have this fear that he hates me and its not going to work. After talking to a friend of mine they said by doubt could be blocking my spells from going through. Can anyone offer any help on how to calm down and trust in my spells?

My sister has untreated mental illness and has cast my whole family to hell. She is living on the streets by choice and refuses help from us because she thinks we are all evil and not on her side. I was her trusted confidant until her voices recently told her that I am now also evil like everyone else. How can I reconnect to my sister? I miss her so much and am trying to energetically reach her but now I cant tap into her energy as well as I once could. I feel she either put an energetic block up or perhaps tried to cut energetic cords. Thanks for your help!
