Stop calling unpleasant emotions negative!
There’re no negative emotions.
You have feelings. Their strengths may vary.
For example, you may feel happiness. You may feel anxiety or anger or anything else.
Naming unpleasant feelings negative creates an illusion of something you need to avoid.
When you avoid them, they aggregate in your body as muscle tension.
So, instead do the opposite.
Recognize your feelings by naming them (e.g. “happiness”, “anxiety”).
Speak them out making that as safe as possible for others (e.g. “When you say that, I feel anxiety”).
And notice the difference!
