I don't think there's anything better you could do than take the thoughts that you shared here and give them to her. See if she's open to partnering with you again now that you've had time to reflect and now that you're sharing with her that while she may have *felt* or believed that she hindered you from speaking, that was not the reason you may have been quiet.

My only question to you would be, did you make some progress with her on your goals? If you did, I encourage you to contact her again.

Therapy will be painful in my experience, it's not the pain we should realistically hope to avoid- but stagnation. I think avoiding self-destructiveness and a lack of progress are good goals, because the work of therapy is often painful and there can be misunderstandings and disconnects, but a good therapist stays focused on helping at all times and has the tools to help you figure out and progress on your goals.
