The point that
@TorqPenderloin is making is that if you restrict carbs, but not enough to get fully into ketosis or stay there, you end up in a no-man's land where you can feel constantly exhausted.
The descriptions in this topic of
@tigerlily72's diet suggests that she is not in constant and full ketosis (as
@nosher8355 and
@Brunneria are) and as a result could be experiencing the downside of an LCHF diet, namely that if you don't do it full bore, you run the risk of feeling constantly tired as your body is not adapted to run on fat and you aren't quite eating enough carbs to provide the energy you need. The OPs posts suggest that she is still eating bread and sweet potatoes so it is highly likely that this awkward half way situation is prevailing.
As
@CatLadyNZ mentions, there could also be other factors involved in the way that
@tigerlily72 is feeling.
Unfortunately on the diet side, it is a case of either going properly low carb and forcing yourself into ketosis, and this means cutting out bread, sweet potatoes, various pulses, certain veg, etc, or eating enough of the right carbs to not affect blood sugar but match the energy needs of the body. There isn't really a halfway house.
