Hoping the end is near

(23F) Currently have completed 5/6 rounds of R-EPOCH and trying to plan my return to normalcy. I stopped working during treatment as my job is in a school and I didn’t want to risk any contact with illnesses, but now I have to start planning when to go back. I was really worried at the beginning of this journey about the side effects of chemo and how I would be affected physically and mentally, but I’ve been surprised at how minimal things have been compared to some of the horrors I had read about. My hair is gone and I’ve gained about 20 pounds which sucks, but the most noticeable thing is the fatigue. My onc has me on olanzapine during treatment which curbs my nausea completely and I haven’t thrown up once. The worst I have felt was probably round 2 where I was having body aches and horrible headaches for days, but since then everything has sort of leveled out. What I’m wondering about this last cycle coming up is should I expect to feel the same as I have for the last few rounds? Or should I expect to feel worse since more chemo has accumulated in my body now? I still have to get my final PET which I am incredibly nervous about because I just want this to be over so badly. I also am dying to get back into a normal routine and start getting out more again. I want to go back to work a couple weeks after my last treatment if everything goes well.
