Feeling invalidated by therapist's lack of empathy

Is it normal for a therapist to say that you’re taking a situation too personally? I had just got back into therapy and this was my first actual session in awhile and so I was explaining a situation I had with my sister who I thought of as a close friend that ended up cutting me off. And so when I explained what happened and read some of the messages to my therapist. She first said “let me stop you right there” and was saying that I was taking the situation very personally and that I needed to see how I could support my sister instead of expressing how i felt to her when she practically ghosted me. And that I was acting like my sister was trying to be manipulative (which I neither said nor thought) and so I was trying to like take myself out of my thoughts and try to understand what my therapist was saying. But for the most part it seemed that my therapist wasn’t empathetic towards me at all and was completely taking the side of my sister? Instead of like seeing both sides or to help me see a different side to the situation. It just felt weird bc I really felt invalidated and I wasn’t sure if I was just too in my feelings or if she really wasn’t listening to me at all. I know when I talked with my sister M who I’m very close too and she’s been in therapy for awhile said that what the therapist was saying wasn’t right and she wasn’t seeing my side at all. And even my best friend thought the same as well. Honestly I’ve decided to go with another therapy company bc it just felt so invalidating and I’m hoping I can have a better experience with a therapist that can see both sides without it seeming like she’s “choosing” which person is right or helping me see in a different light without making me feel horrible about it
