Three things.

First, you likely need a break because you are using some kind of willpower to keep going. The easiest way to not need willpower of your own is to rely on someone else's. You learn to work hard by having someone else working hard next to you. I'm currently working on landscaping my back yard. Each day, all I can bring myself to do is fill up one wheelbarrow full of dirt and then distribute it, because I am doing it all alone. But for the past 4 days, I have been working 8/9/10 hour days of constant physical labor, because I am doing it with a group of people. I don't really care about the project, but I'm getting paid. But the reason I can keep going when I'm fatigued and my body aches is because I see the people around me working, and want to help them. After all, if I don't work, it is more work for them. I want to help my coworkers and do my fair share. I want to avoid being shamed for being lazy, and I want the social praise of working as hard or harder than anyone else. If you really want the secret to being your best self, fhe answer is: love other people enough to help them.

Next, saying you need a break from your break is a feeling I'm familiar with. You know why I need a break from my break? Because I am on my phone. Being on your phone, or staring at a screen, is not relaxing or restorative. If you "take a break" by scrolling lemmy or watching netflix, you aren't really taking a very restful break - at least mentally. Why? Because the way these things keep you interested is by being exciting, and the way to make things exciting is to introduce fear and conflict. These emotions will ramp up ypur stress level and make you feel more tired. If you are taking a break, actually take a break. Sit down and close your eyes for a bit. Lay on the couch and stare at the ceiling. Meet a friend and spend and hour laying in the grass at the park talking about nothing in particular. Be bored. The one thing I know that consistently motivates me to do something is being bored. So if you need a break, throw your fucking phone across the room (case recommended) and be bored for a while.

Finally, if you are well and truly tired, I re-recommend sleep. If you don't sleep well... do it. Figure it out. There are tons of strategies, systems, science, and snake oil. Fucking try shit. The things that work for me:

1. Establish a consistent but realistic bed time. I do midnight.
2. Outside extreme circumstances, no naps.
3. Ensure your sleeping area is as dark as possible.
4. Remove your phone/screens from your sleeping area. Dont do things other than sleep and fuck in bed.
5. Use blue light blocking glasses before bed. They are cheap.
6. If at all possible, wake up naturally instead of using an alarm clock. If you must use a clock, get a sunrise alarm that uses light instead of sound. They are annoyingly expensive.
7. Aim for 9 hours of sleep each night. Experts say 8) But you're gonna fuck up.
8. If you can't stop worrying or thinking, start journalling before bed. You can write down things you are worried about, plans for the next day, etc. Find something that works for you to get the clutter out of your brain.
9. If you can't fall asleep but your brain isn't spinning, doing a body scan/yoga nidra, or meditating can help. I also notice that I feel more rested for the same amount of time in bed when I do these things before sleeping.
