Attritted means you were kicked out of the program. Most people, and by "most people" I mean the very few who get attritted, are kicked out for doing something dishonorable like having sex with other candidates while in the program (I knew of one person this happened to) or lying about something to a staff member. Rarely, people are attritted for being unfit for military duty, usually because they have some sort of mental issues (usually these people DOR instead, but some don't and have to be forced out for everyone's sake). Some other people are attritted because they have serious attitude or authority problems (I knew another person booted for this reason). People aren't kicked from the program just because their Drill Instructor doesn't like them. It's pretty regularly some serious character fault or other incompatibility with the military.
This is why people are saying you will have a tough time reapplying, and why we are saying we can't help you unless you tell us why you were attritted.
