Did I reset?

I started Cymbalta (20mg) laye June. It was amazing for me - I wasn't anxiety spiraling anymore when I went to bed, I could focus, my pain lessened significantly, I loved it. I was only on it for like 6 weeks before I had an insurance/travel kerfuffle and was off of for 6 days before I could get a refill. I feel tired, irritable, and its impossible to focus on work. Did I reset completely? Will I have to wait another 3-4 weeks before it properly hits again? I've only taken 3 doses since I refilled and the difference between on and off of it is very stark. We're entering a very hectic period at work and I cannot bring myself to care and really need this to kick back in so I give enough of a fuck to not get fired 😅

Thanks in advance for any help or insight!!
