What a dismissive comment. Everyone competitive or with ambitious goals has moments where they feel overwhelmed and their mind screams and looks for a way out, and the question is whether you should trust that feeling and look for something that would make you happier or find a way to pull your head up and remind yourself why you chose this situation in the first place. It's totally reasonable to look for advice when this happens, and doesn't show a lack of "planning" - it always feels different when you're in the middle of it from how you saw something originally.
