Anxiety mode activated

I just got a call from an aerospace engineering internship that I really wanted and botched it so hard. Full anxiety attack. The interviewer called me out of the blue while I was walking back from class and asked: “what would you say are your strengths and how will they help you in this internship?” I blanked hahaha I said “ I uuuuuuhhh think that I’m really hard working(voice crack)...and(swallow)....(30 seconds of silence later)” she then said something along the lines of “We will pass your application along for consideration, bye. “Taking a step back, it’s almost funny how badly I just performed. This isn’t even my first interview. Through my previous internship, I had to do two interviews, talk about my college experience(impromptu) in front of high schoolers for 2 hours, and eventually lead a presentation in front of ~70 people. In high school, I purposely chose to work as a server where I had to regularly greet/speak to customers. This time I just went full anxiety attack and shriveled up and forgot EVERYTHING. But I can’t help but think that this was a long time overdue. I’ve struggled with anxiety for a long time. I’ve had small instances like this when talking to people. I’ve done my best to force myself to be in social situations but I have never found a way to improve my social performance. Anyone have any tips/input?TLDR: anxiety mode activated. Phattest L of my career. I don’t know what to do.
