I agree. It sounds like a very tough session. Was there anything redeeming about it? Anything that made you think "on the other hand she was lovely/validating/astute in this other area?"
I think go with your gut here.
Yeah, I agree with the idea of telling T "when you said x I felt y" but really saying "so basically, you're on speed" is insulting and whatever her thoughts about LD she should bite her freaking tongue until you ask her opinion about it (or until she knows you better.) Those difficult conversations where you bring a major misattunement to the attention of your T should not need to happen in the first session. She she be working harder to make you feel safe, welcome and understood.
She sounds unskilled to me. For eg she could have said re: your paper "how did you become interested in that topic?" That would have shown genuine engagement and if you did want to talk about any experience you may have had with those drugs, she'd have opened the door in a non-threatening, non-accusatory way.
I would look for someone else.
