Is it possible to drop out of Army ROTC?

I'm currenty a non-scholarship MSIII who just got in through the Alternate Entry Option (No LTC, going this summer). Problem is, I'm not doing so well in the program. My inexperience leads to horrible evals in many events (they like to throw me in leadership positions right away without giving me some familiarity with the position) and many of my fellow experienced cadets don't want anything to do with me, much less help me when I ask for it. I was just contracted last quarter, and I only receive a stipend for my efforts: is there a way out if this becomes too overwhelming?
