Have you ever feel frustrated with client?

Hi I was developing WordPress site for my client. They really don't know actually what they want.. First they said I want this this ...then when we are done they said we want different. Then again redesigned then they provided their own design. I really feel sad about it. I have given so efforts then again. How my community members handle this kind feeling or have you ever feel this? Any kind advice or suggestions would be really helpful for me. Thank you 🙏
