Why is it important that a therapist care?

I struggle to think my therapist cares. She asked me today why is it so important?

I don’t have an answer. I just thought it is normal to want that because I tell her many difficult things, and when I do that with friends and get a supportive response, that to me indicates that they care.

Why is it different with her? Maybe it’s just so intense with her that could me it’s something else? Something that I looked for as a child?
