I encourage you to reach out if she's expressed willingness to take your emails or calls. I'm sorry you're feeling overwhelmed. I know how that is. Writing to my T does help. What other coping skills can you employ in the meantime?
Sometimes when I get overhwelmed about my trauma, I go into a special room I created with my therapist, a visualization, and I mentally lock myself into that safe space and enjoy the surroundings.
Exercise outdoors helps me too.
Soothing with a blanket, music, tea or other comforts can help.
Hope you find something helpful.
