It seems like T's intentionally give too little support in order for clients to be challenged and also so they don't make clients feel dependent on them to solve their problems, if you do become dependent it can be really hard to break the habit. T's usually decide how much and how little contact is ok, since it's their personal boundary to set. You should definitely discuss it though!

About doing the deeper work, I hope you reach a point where you want to take the risk and trust your T to press on. Like anything in life there's odds your T might burn you after you open up, I like to think those odds are low. In reality it's moving on where things can get better, your T will actually probably be more engaged in my experience.
