You don't need to meet all criteria of Schizotypal to have it, for example I don't necessarily act eccentric and odd, I'm very quiet. There's more than likely a couple of things playing into it. I've been diagnosed with Borderline with suspected Schizotypal and Avoidant, as well as a possible DDNOS. When this happens, the illnesses tend to overlap and it becomes a bit more harder to work out.
