I'm sorry you had such a negative experience with this woman. She should not have said what she did. Clearly she has no idea what she's talking about. Your coping mechanisms are great, safe, healthy ways of dealing with your depression and if they work for you, then I fail to see how they could be considered "useless." What you're doing is GOOD for you and you should be proud that you're taking such positive steps in your journey to recovery. I journal too, and I find it INCREDIBLY therapeutic. A LOT of people do. What planet is this woman from?!
I do hope that you lodge a complaint. It's terrible what this woman said to you but maybe you'll be able to help prevent her from ruining someone else's experience with the crisis line in the future.
