It's Kismet that you brought up bipolar - Smiles
It happens I know some people who are classed under the Bipolar Umbrella - General Anxiety Disorder, Manic-Depressives, Suicidal tendencies, Schizophrenia, and a couple more I can't remember. It can be anything from a minor symptom to all-out personality disorders bordering on insanity. I personally am glad it is a condition that's over-diagnosed - it might've saved my first marriage had this been a more well-known or well-publicized medical condition. Problem is that Bipolars don't think anything is wrong, mask/hide the symptoms, blame others or other circumstances for their behavior. My ex still doesn't think there's anything wrong and it's everyone else's fault for his/her uncontrollable behavior. My ex mother-in-law and her sister were Bipolars and had bizarre behaviors - seems to run in families. Without treatment behaviors get progressively worse with age.
Poor actress Patty Duke thought she was crazy until she got properly diagnosed and treated which is another whole bowl of wax to go through to find the right combination of medications to treat it. Bipolar used to be a stigma but with proper diagnosis doesn't have to be anymore just like Autism, CP, ADD, etc.
Yes, Bipolar can be a sensitive issue but I don't think it's confined to humans - I've seen some bizarre behavior in some of my hormonal hens LOL
I am diagnosed with Bipolar. So I know some people can be very sensitive about it too. Maybe not the next day. U just never know. I went though several years of hell!!! Come to find out, my hormones were completely insane! So, 1 pill a day now helps my BP, and hormone therapy combined, I can actually function most days! But if I forget to take either..... Look out kiddos!! Sucks, it just is what it is.
