My sister is a scientist/lab rat and she LOVES it. Originally she was a nurse and did work in nursing for a few years. She enjoyed it but her true passion was science/lab work. She went back to school for a second degree that she completed last year. While she was in school she worked as a processor in a lab and now she works in the stat lab of a large county hospital and she LOVES it.
My sister and brother in law made tremendous sacrifices in order for my sister to go back to school. In the end it was so worth it. My sister loves her job even though it is grueling and tedious work it fuels her with passion. I call her the "Lab Queen". I guess I should say I view her work as grueling and tedious. To her it's a new adventure and problem to solve each day. I about barf when she tells me of the specimens and samples she has to analyze each day, lol! But to her it is pure joy.
Just reading about my sister's course schedule when she was in school made me want to cry (and puke, lol!). She is an absolute inspiration (and a totally smarty). If you like the medical/science field then go back to it. There is no law saying you have to take all the classes at once. Hell, take one class each semester.
You know, this is the FIRST time I have ever heard you post about something you truly enjoy that would be just for you. If I can do this (and keep in mind I am the original hot mess then you can!
then you can!
