Too much action?

I’m beginning to feel like I’m maybe taking too much action? Or maybe it’s all going in the wrong direction. I’m feeling physically run down and won’t allow myself to quit business building and learning marketing and…. I’m almost bedridden with exhaustion but I’m wondering if it’s in my head. And I really want to take a day off and feel ok about it but then I’m worried I’ll just lose momentum. I think I’ve been constraining my focus to business at a detriment to my body and worrying that I’ll run out of money, even though I have assets I could sell and no debt. I find my thoughts getting more and more negative and I’m resenting showing up for clients and meetings simply because I’m tired, I know I need to reposition some of the focus on nurturing my health. I may be buffering with work. I guess I didn’t think it was possible to buffer with work, but my brain might be sneaky that way. I have a place to live, I have food, I have passive income… I don’t even technically need to business build for survival. But… I’ve convinced myself I do. I’m just terrified to let go, cut back on hours, get a checkup, somehow I’ve equated this to failure. Where to start?
