Raising prices

Hello, I have a question regarding the feelings that I have regarding my prices for coaching. A few months ago I almost increased my prices by around 70 percent. At that time I was fully booked and I decided to shift into group coaching and offer higher prices to those who would like to continue 1-1 coaching. I felt sure about my decision at that time. However now more and more often I feel that I am charging too much. I feel shame and guilt when I tell people how much my coaching is. I also feel that I need to work twice as much to prove that my coaching is worth it. To my surprise, more and more people want to work with me at a higher price but I constantly doubt whether they see the value in cooperating with me.

My question is – how to feel confident about the new price?
