Confused about possible nursing career..advice needed!

Hi everyone. I am a 21 year old who just finished up a medical transcription program last month. I enjoy it somewhat and am able to work at home, but I'm realizing maybe I don't want to work at home! Nursing has always been on my mind. However, I tried to take a CNA course a couple of years back and dropped out. I had missed a couple of days and gotten behind. Also, I was VERY nervous about doing things in front of other students, and I mean extremely nervous. Is there any way to get over this?? Whenever I think about what I want to do in my life, nursing pops in my head. Sometimes I feel like it is what I am supposed to do. I worked as a patient aide at a LTC and enjoyed the patient contact and effect I had on them immensely. One thing I was considering is taking an LPN course, thinking that it might not be quite as stressful as going right to the RN. I've changed a lot since I took that CNA course, but am still anxious sometimes around other people. Any advice would be GREATLY appreciated!
