Let's face it, surgery is a major injury to the body, even if it is controlled and done for positive health reasons, but it takes it out of the body. You have lost body fluids and the pain pills and the IV stuff also needs time to heal and you do not have the stamina you did before for a while. Stress from stuff that is not healing right, or is not yet healing is also going to drag you down beyond anything you may have imagined. The dilation is symbolic of the whole damned healing mess, and thus, gives you the final message that you are too danged tired. I am diabetic and am surprised that I healed as uneventfully as I did. At 18 months I still have draggy days, and as I just said in another thread, the dilator is no longer a pain in the Vagina, but it sure is a pain in the neck!!
