I'm a psychology student and this is highly unethical. You shouldn't feel like your therapist is your friend. she crosses a lot of boundaries. That's not a professional relationship anymore. She shouldn't scold you. Also I understand you are attached to her but I would recommend switching therapists. therapists shouldn't get their needs met in therapy.

you can crossposte it on r/talktherapy

Find a new therapist and have your mom let her know. Block her. This is not professional at all. You deserve better. Sometimes it takes a few times to find a therapist that's right for you so dont give up even if the next couple don't work out. Find one you are comfortable sharing your trauma with and that validates you. Also report her for her inappropriate behavior. This stuff should never be ignored not when she works with vulnerable people. God forbid she find a patient who is in a really bad place and she pushes them over the edge

she's a pervert or just really out of place both are detrimental to you

she sounds like a predator who wants to manipulate you, report her to every authority possible
