anxiety and exams

i just learned i passed a uni course i had difficulty with. i was repeating it, got moved to a different year group because of it. anyway, i was over the moon when i read that i did it. yes i got a passing grade and nothing higher but at that point with how much stress i got because of the exam i was so happy to be done i was jumping around like an idiot. it is insane how fast and how hard my heart was beating when i got the results email and couldn't open it, i sat in one place for at least an hour with shaking hands. i thought i would die. so afterwards i called my mom and told her that i passed it, she knew how anxious i was and my several mental breakdowns after my final exam because i was really worried for it, i was so anxious in the exam room and i forgot half of the stuff, you can imagine how disappointed in myself i was. i felt happy about telling her because i thought she was supportive and understanding after my exam, she said she wouldn't care about the grade. now she told me she's dissatisfied and confused. she told me, and put great emphasis on her point that "i want my anxiety" ???? and that i can just "make it go away" any moment but i "dont want to". what? who else apparently likes not being able to breathe and feeling like they are going into cardiac arrest 10 times a day? looking like a psycho because their whole body is twitching from nerves? i was happy for exactly one moment now im sitting here crying again.
