Hi, I'm A 19 Year Old Female. Recently I've Noticed

Hi, I'm a 19 year old female. Recently I've noticed a rise in my anxiety. I am looking for a job but keep purposely missing interviews because I am too nervous of meeting new people and messing up and being embarrassed. I constantly feel like people are looking at or judging me. Also, I cannot focus on any tasks I have to do for the day. My brain feels so scattered. I cant sleep at night at all, falling asleep around 6am every morning. Is this something Ishould see a doctor about? Also what would they do?
