How exactly to do that depends on what works for her. Maybe she finds that if she steps back and gives herself some space, and then pulls one thing in and makes it more clear and close, then she doesn't feel frustrated. The thing is that the person doesn't just have vague, random reactions for vague, random reasons. There are very specific perceptual distinctions being made in specific sequences to get specific effects. If we change the perceptions, the reactions will change.
All perceptual distinctions have controls, most of which are sliding scales.
There is a quality or quantity that you can control to make more of it or less of it. Some of these controls are more important to an individual than others, and different positions will have different effects. If you find that a big picture makes the associated feelings stronger and a small picture makes them weaker, well, there is an excellent tool. A tool that you can very easily put in somebody's hands. The client just needs to learn to make her positive self-image and her positive goals bigger, and her fears and anxieties smaller.
