You're reminding me of my first stint in group therapy. Youth would nearly always overlook me. Some blatantly insulted me and made statements such as "Intellau, you know no one wants to partner with you. Go over to the table and sit alone", "Tsk"(Directed at me), "No one likes him! He acts like a female! Why do I have to go to the 'Quiet Room'?".
The only exception was when a certain kind youth joined my group. He treated me respectfully and showed concern for my obvious anxiety and social ineptitude; I was his partner for one group assignment, and it went very well.
