ummm There must have been something else going on with the person other than Bipolor.

Bipolors dont have major "switches" they cycle which is one of the diagnotic criteria for being bipolor - they have major highs and major lows but unlike a normal depressive in between they go from high to low in a "cycle" - it is a cycle of DAYS of progressively their moods goes lower.

for example going from high to low - each day its a little harder to get out of bed. each day its a little harder to do the daily activities, each day they feel sadder until finally at the height ot that cyle they're at their worst cant get out of bed, cant do their daily activities, constant crying, and sadness. Then they start cycling back up again - each day they feel progressively better start being able to get out of bed, start doing their daily activities again stop crying and are a bit happier. then they reach their highest point of being top of the world happy, very active and dont want to stay inside and in bed. Some people at their highest point are hyper - cant sit still always having to so something. then they cycle down again with days of progressively getting sadder, having trouble doing their activities and so on until they bottom out at their lowest point again.

If they are on medication and it is the correct one and dosage they dont experience the cycling but stay at an even level in the middle like a normal person.

Bipolors dont suddenly "switch" into uncontrolable behavior.

I have been in the depression / anxiety management group open to depression, anxiety and bipolor people that my therapy office offers now through three different sessions. Each time the instructors were different, but they all using different material explained the "cycle" of depression and bipolor and anxiety. Each time the bipolors attending were different people in the group. Not one of those bipolors that were in the groups with me "switched" into uncontrolable behavior. That person had something else going on other than bipolor which is quite possible a person can have bipolor and depression and anxiety and have other disorders too. Don't let that one person effect your attending other depression groups. that happening in groups is very rare.

Addition-
I recieved a pm with some bipolor info. I did a quick check on the resource I was given - Bipolor World.

It explains the rapid cycling -

A person with Bipolor can cycle through the highs and lows at a fast and very fast rate. Sometimes within 24 hours. Basically according to this source the rapid cycling is not the persons regular patter of cycle as in they don't normally cycle through their complete patter every day on rapid cycle. Something happens where the person goes through the normal cycle of going through from highs to lows in a progression only instead of the cycle taking days it takes 24 hours - first really high happy energetic, then a very quick progression of getting worse then hitting their lowwest point of not being able to do anything, very sad, and so on and then the very fast progression upwards until they hit their highest point.

the rapid cycling isnt the persons permanent cycling patter, just an isolated situaion in the persons normal pattern.

Rapid cycling does not include uncontrolable behavior just the same as a normal pipolor cycle only very fast.

Thanks mandy for that bipolor world resource Im going to keep looking into that one.
