Believing I help people

I am recognizing a thought that comes up in my healing work, “I don’t know if I really help people” or some variation. I’ve had people tell me how profoundly the work I do or the plant medicine I make has helped them…and yet I still struggle to believe that I have the capacity to profoundly help and serve people. This is of course a HUGE problem when it comes to having a business serving people, because I am constantly negating/doubting myself and not recognizing the value of my work. And not showing up properly or making offers to help or even figuring out how to talk about it, because its fairly alternative healing work. I want to get to a place where I believe ” I have the capacity to profoundly help people” and really BELIEVE in myself and my work but I’m struggling to get there. Any thoughts?
