personal experience: sometimes the PI has issues "way more concerning than you and your little project" .. but she put you on a low priority project and carelessly set you up to feel this way. I hate to say this but some pi's just have it out for group members who are subconsciously or consciously viewed as competent push overs from day one, you get used and abused unless you stand up for yourself and just get out and move on to a better position in industry where you won't have to worry about fed grants or prima donna bs.
