Should I leave my therapist?

I've done about 10 sessions and she has said absolutely nothing at all in them. I have just been made to talk which is something I do constantly in my head, diary, notes app, or videos myself. And she had planned on sending me an EMDR schedule. She never did. It seems like time is just being wasted as I talk. She's good at some things though, like she gives me extra time for free to finish talking about something more. But literally no input has been given. And yesterday, I was panicking about something so sent her like 50 messages on WhatsApp and she responded to a few very generically. Then I sent more, and she said she'd respond in an hour. It's been two days and she hasn't responded to me. As I have all my life I have calmed myself down. It just feels like she's doing nothing and wasting my time. What should I do?
