"I didn't want anyone to talk to me," said Harry, who was feeling more and more nettled.
"Well, that was a bit stupid of you," said Ginny angrily, "seeing as you don't know anyone but me who's been possessed by You-Know-Who, and I can tell you how it feels."

I don't quite get the meaning "seeing as you don't know anyone but me" in this context. Probably, the phrase "seeing as" confuses me. How should we understand it here?

The phrase "seeing as" is a way of introducing a fact. The sentence could have used other words that convey the same idea, e.g.:
It just means that Ginny is explaining why Harry was stupid for not talking to her.
As for the "anyone but me" part, that is Ginny's way of saying that she is the only person that Harry knows who has had this experience. She is saying that Harry doesn't know anyone who could help him here except for her. She can help him because she has also been possessed by Voldemort before.
