The wisdom these days is that you cannot be diagnosed for bp without a manic or hypomanic episode -- basically because without the manic end of the spectrum the condition is (unipolar) depression rather than manic depression / bipolar.
A couple of good pages you could check out for more information on manic / hypomanic episodes are:
I think the way you describe not being sensible when it comes to soothing yourself is very common for depression -- especially when linked to anxiety. I am very much like that myself -- and I am a unipolar depression with anxiety gal (on this board because of my ex's bipolar). It sometimes takes a while to find the right meds for that too -- as well I know lol -- but I have eventually managed it with the help of a patient and thorough doc. Always worth pushing for more investigation into the meds side of things. :)
When I'm not in my right mind, my left mind gets pretty crowded...********************
Things are going much better since the med change. No more depression, the Depakote takes away the anxiety, so I don't feel like using Xanax (which I'm tapering off of now), and the Seroquel+Depakote makes me sleep like a baby without the Lunesta. Mine was just an all the time feeling, like my brain wanted to jump out of my skull. All this started happening after I got sober 11+ months ago. I guess those 23 years of self medicating finally wore off.
