I think that when we (people who have bipolar) have an infection, other illness, etc, that it often causes imbalance and affects our stability during the time of and during recovery from the illness, infection, etc.

It does sound like you are having depressive symptoms. Let yourself rest, and also push thru as best you can with self-care. (eating meals, shower, a little bit of housework, going for a walk if possible, etc).

Let us know how you are doing.
