There is another antidote, although it is not new nor is it always the answer we seek or need. When confronted with negativity, face it in battle. Be bigger than it, dominate it, fight like your life depended on it. You are stronger than you think. Find that strength.
Most importantly, you are not alone. Seek this "warmth" from good friends and family; shy away from the toxic things. There are some awful things roaming about, true, but there is also so much to be thankful for. Keep your loved ones close.
