In an ideal world where all are good therapists, it would be best to present how you feel at present. If there is not a good experience, or mocking in any sense, run! But I truly do know that all is not as it should be. And sometimes, we have to grease the skids. That is NOT how things ought to be, but we are agents of our own change. Perhaps, the best is start out with how you feel you want to, and alter things going along if needed, though there is danger any road you take.
Your life, your journey, remember. The therapist is your tool to help. If it isn't the right tool, change it.
Namaste, Lunae
