ltc staff educator offer

I have been a RN for over 15 yrs. I have worked in hospitals, home health and management BUT not in LTC. Want to get out of hospital nursing, try something new. Have offer for staff educator in LTC facility. Also would be assisting the DON at times. I am more of a quiet person and question if I could do a good job as the educator in some place new and with no LTC experience. I enjoy working with people but am afraid in an area I have not worked. Am I over reacting or any advice would be helpful.
