How do I stay motivated when my dissertation feels pointless?

[Tamina]

I'm in year five of my PhD and I've lost all motivation. I used to care deeply about my research question. Now I just want it to be over. A dissertation coach says: “It's normal to hate your topic at the end. The goal isn't passion anymore; it's completion” . But how do I push through when every word feels like pulling teeth? I've tried writing in different locations, setting small goals, rewarding myself. Nothing works. What actually helps when you've hit rock bottom?
