I have definitely been there. Once you get too tired your brain doesn't work well enough to tell you you need breaks. Your brain after a break (e.g. a week's holiday) just feels completely different. What I do now is this: My first task after coming back from a break is to book a week's vacation ten weeks from that time. I work ten weeks, and take a week's break, that's my rule. Even though it will be difficult to imagine I'll need a break after I've just come back from one. Book it on the company's vacation planning tool if I'm employed, or on my calendar (and inform my customers) if I'm self-employed. I don't worry about where to go, or what to do during it, or try to find the best time to go based on events I might be invited to (which I might not know yet), or which projects I'll be working on and when the best time for a break would be to fit in with them. A break isn't about any of that.
