Bea Thank you for having the courage to post what many reading probably feel.
KathyLauren gave you excellent advice. I will add my 2 cents. Well in my case it usually turns into more like 25 cents

This is a journey and the path is foggy. It takes time to figure it out. But you have started. I have some thoughts about your post.
Your therapist may or may not be the right one for YOU. Their job is not to tell you the right or wrong path or how you should do this. Their job is to help you find that for yourself.
I believe gender is a spectrum. Cis, binary trans, non binary, gender non conforming etc etc.
You are who you think you are. But you have to search yourself and it may not happen overnight. Listen to your heart. You know the answers deep down. What blurs our insight into ourselves is fear. What will people think? How will I look? Will people think I am crazy? On and on and on.
We have to live as who WE are. You have one life don't spend it hiding.
You mention your appearance. Mine kept me in the closet for 55 years. I am 6'2" 200+ pounds - I look like a football player. That is why I told myself I didn't transition. The real reason I have learned is I cared what people thought about me.
It is tough to beat down that fear. That is the reason for my signature line below. We can help you but most of all it has to come from within.
I have only had an orchiectomy and HRT. I am no beauty but what I am is a woman. Legally - my birth cert DL etc etc. but more importantly I know who I am. Deep down you do too.
I am going to post a couple pics of me below to prove my point. If I can do this ANYBODY can do it including YOU.
1st pic a day before I started electrolysis. 2nd about 6 months into transition wearing a wig. 3rd sometime last fall with my hair grown out.
Do I look that different? Not really. No surgery, no shorter just an orchie and HRT. You can do this.
