hi.
first off, don't feel bad for posting after all this time.. it's okay. that's why we're here.
i'm not the best at giving advice, but if it were me in that situation- I would be honest with her. I've always been taught to be honest, especially with professionals like doctors and therapists.

sooner or later, she'll probably want to talk about it anyway.

does your therapist allow emails or phone conversations when you're not in session?

it may be an idea to tell her... hey, I appreciate what you're doing with me- but I feel such and such needs to be addressed first, and maybe explain what happened before

it's not always a bad thing.. depending on her personality, she might actually listen to you and address these feelings.

this is only 1 opinion, and it's coming from someone who tries to be open in sessions

just know that.

good luck..
