I think the ideal would be not to be freaked out about possible episode... I know it's like en elephant in the room... but the more you think about it, the more likely you are to bring it upon yourself. So NOT overanalyzing every tiniest feeling is the thing to go... I stopped mood charting for this reason... because I realized it was enhancing the bad feelings.

... but I just came to accept that these come and go. I deal with it when they come. I use all my strenght and all my tools to hold together. Mine episodes aren't superlong though and I learned (with years) to somehow manage them.

sometimes one has hard times stresswise... in such times,I prefer to thrust myself onto the work and put myself and my feelings in the background and sail through. If the stress is going on too long, one may reconsider if this is how they want to live (yes, I know changing your life is not easy... one has to consider what is worse.... live like you are for years to come, or risk and change things? Is the frustration long term or are you having bad time just now?).
