I totally get you. Just remember there is no cure for bipolar but it can be managed. Sometimes we have set backs, (even if you have been doing well for 5 yrs.) and we just have to give more attention to ourselves at those times and if it means taking a few days off work to just chill and regroup by doing what we have to do to get to feeling better we do it. Don't sweat it, it happens.
I'm sure you will know when it's time to call the pdoc. But first start with what you know you should do. Everyone has given you great advise so far.
Hope you're feeling better soon.
