Thoughts about my hourly rate & a model

Hi, I feel a little confused about my own thoughts about the hourly rate that I charge my clients. Part of me is like, well, it must be fair because they continue to give me work and pay my invoices. But then  I also feel kind of bad about charging “so much”. Is this just a matter of appreciating the value I’m providing? Or do I lower my price so that it feels like I’m providing more value than I’m charging for? I think if I were to do that though, I would feel like I’m underselling myself.

Here is a separate model.

C: Client said ” Do you have time to chat tonight for 15 or 30 minutes about another project?”
T: I’m in trouble
F: fear
