how do you do it?

We're 34 weeks tomorrow, and she has 'engaged' herself into my pelvis. BH are more intense, diarrhea, shortness of breath, nausea, extreme fatigue, and crazy discharge. I'm still working and plan to until the due date November 14th, and I was wondering how you guys keep energy? I feel like I'm always slumped and can barely even walk to the bathroom. I only work 3 hour shifts for 3 days and one 5 hour shift for one day but I feel like I'm dying 😭😂 Any advice on how to keep myself going? Energy and ambition wise?
