Aids work so hard and are paid so poorly--it should be a crime!
As others have said:
Anywhere you work, you'll do your share of lifting, cleaning, and feeding, but in most environments it's only a *portion* of what you'll do as an RN--it won't be your whole day.
Is your first semester of clinicals in LTC as well? If so, just be prepared that you will be practicing basic caregiving there, so you'll be doing more of the repositioning, lifting, bathing, feeding stuff there, too. Once I moved on to other rotations, I started being involved in other aspects of care as well--giving meds, doing full assessments, etc. As you progress in school you'll see how your role will expand.
I wouldn't at all take this experience as a sign you shouldn't be an RN. Being an RN involes much more than the basic caregiving you've described.
Just never get too proud to make a bed or clean up poop!
The best floors I've seen have been the ones where everyone works as a team and the "messy stuff" isn't left exclusively to the aids!
