I have a friend recently was going though a depression moment, she was misbehave herself and got suspense from school for quite a while, her school had recommend her to student counseling service to see a therapists, and until now she still haven’t heard any update from school about her re-entry for cles, all she got is a letter from the dean of institution said her submitted plan wasn’t prepare for the future academic success, does that mean she wasn’t able to going back to school??
