Too dysregulated for therapy?

My therapist suggested I get too dysregulated in some sessions to properly communicate/advocate for myself in therapy and suggested to take an anti anxiety pill before the session to calm myself and stay in my window of tolerance.

I have had another therapist before also tell me my emotions were too intense/I get too dysregulated.

When I get dysregulated it usually looks like: something the therapist says triggers me into crying/sobbing and me trying to get through that and gather my emotions as much as possible while also trying to stay with the feelings and go through the processing.

There's definitely no amount of rage, or anything inappropriate directed towards the therapist.

I feel really confused. It's like I need to have my emotions neatly processed before coming to therapy. But isn't that what therapy is for? What I would like in those moments is for the therapist to step in, notice how dysregulated I am and help me back into a regulated place but instead she is saying I should take an anti anxiety pill to stay in my window of tolerance. Is that normal/something others have also been suggested to do?

I can certainly compartmentalize, push things down and not get outwardly emotional if necessary. I do that all the time in my day to day life. I thought therapy was a place where I can openly sob and break down when I need to but maybe I am misunderstanding it? I'm really confused. I feel like my emotions are too much/too intense even for therapy.
