Issues when talking to Advisor

Recently I've had to talk to my advisor to pick classes for the new semester. I mentioned that I wanted to change to an education major so I was referred to someone else. As soon as I sit down I get told that my GPA isn't high enough to switch (which is fine). I understand that but she starts to get upset with me because I came late in the semester to advise. I want to preface that I'm only in my second semester of my freshman year which was very bad for me anxiety wise and I still don't know how everything works becausei don'thave friends on campus. She begins to say that I am not cut out for the major that I wanted to switch to because of my low grades and not being on top of things. Which I understand but she wouldn't stop to give me advice on what I should do (there was also a mix up with my classes so I'm behind now). She proceeds to get angry at me for this, asking if I had any friends at all who could tell me these things at which point I was terrified and about to cry so all I could do was say no. The rest of the time I had with her just made me feel like I was a loser and won't amount to anything. After the meeting I threw up in the bathroom and wouldn't stop shaking, it's been three days now and I still can't relax and I just feel scared and sad. Now she might be my new advisor and I'm afraid of her, I don't want to even mention my social anxiety because she just assumed that everything I told her was a lie anyway. I'm so confused and scared.

I just feel like Professors and advisors just automatically assume you have everything together when in college. I can understand it to some point but it's like we're not allowed to make any mistakes at all. My family agrees with them so I just feel crazy when I have panic attacks about "stupid" things in classes.
