WHAT PART OF THE HEALTH CARE FIELD IS THERE WHERE I CAN WORK ALONE?

Ive been a LVN for 7 years, and recently dropped out of the RN program a few months ago. I couldnt take it anymore...I HATE NURSING... Im thinking about being an ultrasound tech? I need something where I can be left the hell alone..please offer your sincere suggestions and be polite please
