I need advice regarding mental health therapy.

Hi, I don't know if this is the best place to publish this post but I'm living in a bad situation and I really need help. I've already tried posting on other subreddits that may be more suitable but I haven't received any responses of any kind. I thought that maybe people a little similar to me maybe or who maybe have had experiences in terms of therapy could advise me. If this is not the right place or if you think it is more suitable elsewhere (and you have any suggestions for me in this regard) I will delete the post.

I started going to a psychologist a few months ago because I have been living in very difficult conditions in my life for years and I have developed many problems that do not allow me to live my life to the fullest and create limitations for me. I'll try not to dwell too much but there have been various events during my therapy in recent months that have somewhat alarmed or annoyed me but I thought that perhaps it was I who was taking the thing in a wrong way or that I was misinterpreting it. In general I didn't feel good about some things but at the same time since I've been going to the psychologist there are some little things in which this experience has helped me and made me feel better, for this despite the negative sides of things I haven't liked them, I kept going. But now one last episode happened that made me feel very bad and I feel that my psychologist has betrayed my trust. There are many thing going on my life, at the same time I'm studying at the university, I'm working and I don't have my own car, so I can't move freely as I want. Since unfortunately my shifts often change at work, I found myself having to change my appointments with my psychologist often. Despite this I go to her at least twice a month. Today I called to have a new appointment because I had to cancel the last appointment due to work, she answered without realizing she was on the phone with me and while she was talking to another person I heard her say these words:

"Wait a minute, I have to give an appointment, to a little girl (in my language it's a way to refer to a young female adult or it's a derogatory way to indicate an immature person), this one (also this is a derogatory way of talking about a person) (she) does as she pleases, she comes, she doesn't come, a mess".

I'm not a native English speaker and when translating the speech loses the negative tone of the statements made, but the words she used in my language are quite derogatory. This made me feel really bad, I pretended I didn't hear anything, but I was about to cry. I live in a heavy and delicate situation and I thought my psychologist understood that despite my problems I'm doing my best to commit myself to going to the sessions because I need them for my health.

It hurts me to know that having to move appointments for work needs is labeled as "doing as I please", as if I enjoy moving appointments. This comment from her makes me feel that she has not understood anything about my situation and about me and I feel betrayed because I have told her so many personal things and it is difficult for me to open up on these issues.

I no longer know how to behave with her, I no longer know whether to continue going to therapy or not. Maybe I'm doing something wrong? Could someone give me an outside opinion or advice on the situation?

I apologize for the rant and for any errors, since I'm not English. I've always seen a lot of humanity in this sub reddit and it allows me to see that there are people who care, I hope I'm not misplaced in posting here.
