Therapist kicks me out after 15-20 minutes

should I get a new one

Tell me more about the situation? Or do you mean it happens often?

I don't think any session is less than 45 mins (maybe half an hour somewhere?) but it's hard to say with so little information. If a therapist is kicking you out, well, it doesn't sound good. But as someone who struggles to leave every single fudging time, I have been "kicked out" a few times but that's different, I think. First of all.. that's when the session has actually officially ended. Oops. My bad.

Yes, you should probably get a new one, but I would try this first:

BRING IT UP with the therapist! Ask what's going on?
