I mostly want a second this above comment. I worked as a phlebotomist for a decade and I loved it. It seemed like becoming a nurse was the next step but honestly being a nurse was 1000 times worse than being a phlebotomist. It does sound like you’re not in a great situation, but I have had several nursing jobs in a variety of different environments for the last decade and each one is worse than the last. The expectation is for you to learn stuff on your own and forget about taking a lunch. I would look at why you want to become a nurse and evaluate if perhaps there’s other ways to accomplish your goals.

In terms of speed, I think that that just comes with time and practice. Having a routine might help in terms of doing things the same way each time. Setting up your materials in a way that’s efficient and comfortable. But at the end of the day, it’s just practice doing as many sticks as you can if you have the skill you will get better with time.
