How do you handle it when part of you doesn't want to go to therapy?

I know little me LOVES therapy. She loves our therapist, loves going, loves being there, misses him when we're not there. And grown up me likes him, thinks going is the right thing to do, knows we should persevere even when we are uncomfortable.

But there is a part of me that DOES NOT WANT TO GO. DOES NOT WANT TO TRUST HIM. Thinks we are a bother and he wishes we would go away. Thinks little me is stupid for trusting him and loving him. This is the me that is going to session today. I can tell.

What do you do when this happens?
