I am extremely frustrated with my advisor. She comes to office only when she needs to take a class. She does not respond to my emails, phone calls, text messages. The only way I can get hold of her is to catch her during time. And she clearly tells she is busy and asks me to come other time. She gives a meeting time and always late or completely misses the meeting. I have submitted draft like a month before and she has not given any comments yet. I am in my 5th year of my phd and I now think I have ended up with a very bad advisor. I once submitted a paper for her to review and she took over a year to review it. I have a job in had. But I want to get my phd. Since I have invested so much time and energy. But I feel I am wasting my life struggling with this advisor. I really need some opinions on how to deal with this.
