Nandm, sorry you are dealing with this. Your posts have helped me through a lot, including this one. It is actually a help in a way to know that even people who have been around here as long as you still struggle from time to time.
Don't worry about not being able to communicate what you really mean to say with your psychologist. Even if you don't say what you mean, it is part of their calling to be able to see through the "fines" and "okays" to what they are covering.
