Hey. I know the feeling with struggling to be honest about it in person. I have a suggestion that may help. Once youve got someone you feel ok with, ask if you can interact differently to help you get it out. Can you write a journal and commit to twice a week writing about the past, the present and how you feel. Or a letter to get it all out. Or homework style, they give you some questions to answer at home where you feel less vulnerable. They can then read these, give you advice on what youve written and carry on. I know its hard and feels embarrassing to say somethings out loud. Find a way you can let it out, you can speak out loud when you are ready.

Could you arrange a dual appt? Have the teacher you trust in there as a chaperone, or to be able to look at them and talk not the councillor. Sometimes having someone in your corner helps.

Youre doing great by talking and finding help. Think of the ways you would be comfortable. It doesnt just have to be an uncomfy chair at either side of a bizarrely low coffee table! You'll find a way that gels with you

P.s. sounds like you have a lovely teacher.
