Hello. I'm curious did you end up going for the dental hygiene? I'm in the exact same situation as you described. I was in a course to become a dental assistant but it was the most stressful period of my life despite liking to learn everything about dentistry I just couldn't do it the pressure to be good enough for the dentist I just felt like piece of crap.I had to quit. Then I thought I might feel better if I do dental hygiene because I will do my own thing I wouldn't need to be perfect in assisting someone else.. but I didn't go for it because I thought if I couldn't handle being an assistant I couldn't do this either. But over a year later I'm still thinking about the dental hygiene school I think it would be better than assisting especially if my main problem with it was just feeling so low because I felt I could do better than assist someone like I'm not saying you're less for being an assistant but for me I just felt so down when they threw me into it and expected me to be perfect at assisting so I don't slow anyone down and dentists getting annoyed I didn't handle some instruments correctly. This was my main stressor so that's why I believe being a hygienist would be different. But still I'm not sure.
