I feel ya! I wouldn't say I'm feeling disinterested, but I'm feeling very overwhelmed at all of the work that Nursing school entails. It's my first semester of college ever, I'm living away from home for the first time, and I feel like I can't keep up with the work!
What I do when I feel stressed is to think of why I decided to go into Nursing in the first place. Even though the classes I'm taking may be stressful, I try to remember that Nursing won't be Biochemistry 24/7, or strictly Micro, etc. That helps me when I feel frustrated with my classes.
Also, I often try to take a step back and look at how awesome what we're learning really is (okay, not EVERYTHING
but still) ... for example, earlier today I was studying for Anatomy and I was stressing because it was just so much to remember...I decided to take a break for a bit and just read a section of my book for pleasure. Since I wasn't pressured to remember anything I was reading, I got to enjoy it and was just completely in awe of the human body and how amazing it is. Then I got really excited because someday (God-willing) I will be able to experience that at work everyday.
That may sound completely corny, but it works sometimes!
