Jobs in the medical field??

Jobs in the medical field?? Hey everyone! 23 year old here. I’m trying to figure out what I wanna go back to school for and wanna make decent money. Is anyone here working a job in the medical field and able to function at them fairly well? I was thinking about being a surgical tech. Also trying to get past the fear of going back to school and having to speak aloud and all of that and inevitably having embarrassing or cringe moments. Any input would help :)
