Anxiety & job interviews

So I had a job interview over the phone today because I am trying to better my self. My current job is a bottom position (that I’m treated as such) and after over a year of applying to all kinds of other jobs I finally got an interview for a great opportunity. I spent the last week stressed about it and wrote up notes and common questions to try to prepare. My therapist told me to practice speaking in the mirror which I did. So I get on the interview ... and choke and start having an anxiety attack. The panel was so nice and understanding and we even got through a few questions that I can’t even remember if I made sense so I’m pretty sure i won’t get a call back. My husband is pretty supportive and tried to make me feel better after but I was just upset and embarrassed. Anyone else have any horrifying interview stories to make me feel like im not the only failure ? Ugh I had just got on new medication too so I really thought I could get through this but I think the whole week of me stressing myself out just did me in.
