I've been trying to work through my anxiety and have been seeing a therapist for a few months now and I will bring this up next week with her but I wanted to know if anyone here had some advice

The last job I had (also my first job) I worked at was a grocery store and I had worked there for a month before they ended up going bankrupt and closing all locations 🤦. My girlfriend (now ex) worked there for a few months and got me the interview, which was out of the blue and happened when I was just over there to pick her up. I was extremely nervous and even with my ex sitting literally right next to me during the interview I froze up a bunch and took forever to answer questions. Pretty much the only reason I got the job was because they really needed someone and my ex vouched for me. When I started working there, I threw up every single morning before work because my anxiety was so bad. They then ended up closing because they were very deep in debt. 

It's been a year now since that job and I really want to apply somewhere and start working. I've been thinking about applying to be a dishwasher as it doesn't seem too anxiety inducing and I won't really have to deal with customers. However, because of my previous experience with job interviews and throwing up daily, I'm really nervous to start applying to places. 

If anyone else has been through similar situations or has any advice I would really appreciate it.
