Wall decor question

[Polabowla]

Now that you’ve said it, I like my bedroom to be serene and for me, that means i don’t want a lot on my walls. Maybe I need to voice that to my therapist. I don’t want to seem oppositional though...

This concerns me
It's not oppositional to voice your needs or wants in therapy.
It's not oppositional to disagree with the therapist.
Not everything the therapist says will apply to or work for you & it's important to speak up about that.
