Give me an advice

I'm a university student and I have this "friend" that makes me frickin frustrated in a bad way. She asked me if I wanna join her in the same company for internship and I said sure. And I should tell you that, she asked me many times to join her. So, of course, I would assume we will be working in the same company.

Weeks later, she is arranging some papers for internship along with her other friend. That day, she made me wait for 2 hours while saying, "wait for me, this will be finished soon. I'm fixing some paper for our internship". But, I had a hunch that I am not included and she only made that excuse to make me wait for her for 2 hours. After a few days, I asked her if she already emailed or applied in any company, she said no. Which made me feel frustrated cos I saw her paper applying to a company when she made me wait for 2 hours.

Now, going back to present. I asked her again which company she is gonna apply for internship. She said, "My friend asked me to join her in this company, what about you?". That made me feel angry so much. I never asked her if I can join her because I am expecting to be alone. But what made get angry so much is the false hope she gave me. And she replied again, "You should join our other classmates' company" LIKE GIRLLL AREN 'T YOU JUST ASKING ME TO JOIN YOU LIKE A FEW DAYS AGO??? WHY ARE YOU LEAVING WITHOUT EVEN SAYING ANYTHING.

Anyway, I already inquired to a company bcos I have a feeling this btch is gonna leave me behind without me knowing.

But my question is, how can I get back to this btch?

Ps. These words aren't enough to express my feelings and if there's something you're curious about which will make u think I lacked on something, please feel free to ask! Also, ESL :]]]
