We encounter it everyday- evil people doing evil things. Even on social media- we have folks that enjoy wreaking havoc with their careless use of words, taunts, and hate. No matter if they simply do it for likes or attention, it's important that you don't spend your energy on it. It simply encourages the behavior. Some thrive in drama.
We often encounter evil in our own families. That doesn't have to be trickier to manage. You can acknowledge someone as blood but also distance yourself to protect your energy. Not everyone will wish you well and have your corner. Recognize that family and friends are those that whole-heartedly support & love you unconditionally regardless of blood relation. You can not force someone to take a role in your life just because it's expected of them. You can't control others you can only control your reaction to them. Having expectations for someone in your life who doesn't value you is simply opening you up for disappointment. It's best to wish them well, pray for them, and move on having the best life you can.
Recognizing these people in your life as quickly as possible will save you a lot of heart ache. I've said it before and here it goes again- not everyone in your life is meant to stay throughout your journey.
