"Roll up on", as in, shove a dog in her face without warning. I'm happy you were able to overcome your fear - I'm assuming no one forced you to do it? That it was an effort you made in your own time, using your own personal methods, and people who cared about you were considerate of what you'd been through until then? I'd encourage any attempts my friend might make to face her fear should she so choose, but it wouldn't be appropriate for me to take it upon myself to ignore her discomfort with certain situations despite knowing how she feels.
