It is very healthy to ask for what we need.
What I am learning through my own CBT therapy is that even if we have to ask a person for exactly what we need, for example "come over to my chair and just check on me instead of being so far away", we do need to remember a few important things.

People can't read our minds - any more than we can read theirs.
Some people NEED and WANT a T who will come closer to them. Other people NEED and WANT a T who will stay in their chair and not try to approach them. Even the most skilled therapist will lean on the side of giving a client personal space. That does NOT mean that they don't WANT to come right over to us. In fact, I think many Ts actually sit there watching us and secretly think to themselves "I wish you would just ask me to come over there to you !!!" They want us to heal and they want to do whatever they can do to help us heal.

So give your T the benifit of the doubt in these situations.
A big (HUGE) part of healing is leaning that it is OK to ask for our NEEDS to be addressed. It doesn't mean we always get exactly what we want. But it is ok to say "I really need you to give me a hug right now!" If T doesn't hug, that is fine. But T should say "A part of my professional boundary is not giving hugs to clients. However, your feelings of needing a hug at this time are very valid and very real! It is healthy to want to reach out and connect with another human in this way. I am very honored that you asked me for a hug."

Bottom line is that it takes work to express those needs in a clear way and expose ourselves this way. I know it is terrifying at times! Esp when we are wounded inside. Just go slowly and be gentle with your inner child. And keep in mind that a T really can't read your mind :-)
