Why is my would-be client looking at me so skeptically? He doesn’t seem to understand my explanations or intentions, wants to test me by wanting me to diagnose his family members as proof I am genuine, has a fixed idea about what I can do to help him even though he knows very little about me and what I do, but seems to still be clinging to me. Is he here to make trouble? Is it best to simply avoid him?

Indeed, you have hit the nail on the head. You were wanting to avoid him when you received his phone messages because you were seeing intuitively that he was a troublemaker, but yet your big heart won out and you called him back and indulged him at length with his many questions about things you thought were simply because of his wide interests and only later concluded he was testing you in a way to see if you agreed with him and then things proceeded from there. He indeed is an agent provocateur for disrupting and depleting healers who engage with him in earnest and try to help. He is chronically unsatisfied and cannot keep the thread going in a way that would help him out of his dilemma of confusion and uncertainty. All he knows is he is suffering and sees his family suffering and will become quite a pest if you let him. So your plan of simply doing some healing for him but disengaging would be best.
