Changed my prices and offerings and now I’m freaking out!

I had a 20 min coaching session in scholars and my coach recommended I only offer what I feel is best for my coaching clients (which is 6 sessions for $1000) and no longer offer one off sessions. Now my brain is freaking out and I’m thinking no one is going to buy what I’m selling. People are cheap and I feel like offering the one off sessions at least gets them in the door (I’m still offering a free session to start). Should I stick to my guns on this and only have the 6 session offering? How do I manage my thoughts to not be ruled by the fear of not finding any clients who will pay this?
