Negotiating freelance rates without the guilt or burnout

I’ve been freelancing for a while now, and one thing that still trips me up is negotiating my rates. Sometimes I worry I’m charging too much, other times I feel drained just thinking about the back-and-forth. How do you all approach pricing discussions in a way that feels fair to both you and the client, without ending up second-guessing yourself or feeling totally wiped out? I’d love to hear how you strike that balance.
