Hi, liam. I have been in a similar situatin with that stuck thinking, the connected feelings abd anxiety, etc., as well as being a therapist. I spoke with my therapist on my first visit about being a therapist and just took a deep breath and told her that i was worried that it would be a barrier. After about half the session, I found my comfort level with her. I encourage you to do something similar. Switching roles is kind of intimidating, a much milder concern than changing genders, but intimidating just the same.
That first convo with her helped me learn to open up more, as well as that resolving those concerns is really easier than our mind thinks it will be. I wish you success, strength and peace in your adventure. Be confident and stay you beautiful self.
