Overheard my therapist shit talking me from the waiting room

I was sitting in the waiting room waiting for him and he was standing right behind the door that comes out to the waiting room talking to a coworker. I overheard him say, “okay it’s the last client of the day, she’s so….” And he lowered his voice to where I couldn’t hear him and had a negative tone.

I don’t know if I’m overreacting but I’m so upset. I couldn’t make myself bring it up to him during our appointment so I just acted normal. Now I’m just stuck filling in the blanks of what he could’ve possibly said.

It isn’t the first time I’ve overheard him talking about me either. The last time this happened was a couple months ago after a rupture. He was talking to a Coworker and said “I really don’t want to see this next client” and went “Ughhhh” right before he opened the door to come grab me.

I know in reality I should just find a new therapist that doesn’t hate me so much, but he’s so close to my house and is the only therapist near me that takes my insurance. I’m just so hurt. He says all these nice things about me during my appointments and it just feels like he’s lying to my face.

Edit: Well I think I’m just going to send him this post and cancel my next appointment. I’ll still see him next week since I’m twice weekly and we’ll talk about it then I guess.
