Letter ends a toxic friendship.
Sandy Sandy Zavala didn't realize she was a toxic friend until she received a letter from her best friend Debbie ending their relationship. That letter made her look inside herself and examine who she really was. We'd been the best of friends for 9 years and all of a sudden things started changing. I started having feelings of anger and jealousy. I went from being a friend to a drainer, and I sought a lot of advice and support from her.
