Letting go of toxic "friends" is just as important as surrounding yourself with positive people. All it takes is that one person that will delight in the back handed compliment or saying cutting or disparaging things. It is OKAY to distance yourself, in fact, you NEED to keep the negativity away.
Friends are supportive and kind and want the best for you. Your happiness makes them happy. Hugs to all of you that have someone toxic in your life. I'm slowly detaching myself from them and wish for all of you the strength and ability to do the same.
