That's expected man. Your coming off of cloud-9 - meaning gear is up and down. You were just very up from the peak of the cycle, now since your missing what gave you your pep-in-your-step so it is expected to fell tired, sluggish, depressed or what ev. Just must remember to stay focused, never quit and it's only temparay feelings that will go away with time.
Time on = time off after PCT is done and then............it's time to cycle BACK ON!

good luck with everything.
