Stick with it!!! I also went into nursing in my 30's and questioned the sanity of this decision several times during nursing school. Now that I am working I absolutely love it. Yes it is difficult, you must clean up poop and deal with extreme sadness when a favorite pt passess away, but don't let those nurses get you down. Nursing is the most rewarding thing I've done. During your clinical rotations, find out which RN's are supportive of students, go to them for help, and thank them for their assistance and patience. They will appreciate it. Ignore the ones who tell you to get out. They are burned out and probably need to get out themselves but cannot.
