Miss laura, my sis who is bipolar 'sees' things as you do. thank goodness i don't experience those things as intensely. however i have what i call my manic colored clothes- bright pinks, turquoise etc and when i buy them they seem perfectly fine/beautiful. my closet at one time had two long sides. i put all the manic colors on one side and the subdued colors on the other. it was a scream.
as for decision making-when manic i make decisions that seem perfectly obvious. i do this with complete abandom. the decision seems an excellent one. sadly it's the other way around. i am impulsive when i am manic re these decisions. i have to try to be cautious and wait a bit cause i am aware when i am this way. being aware of my ups and downs (more frequent) has helped but took time to recognize the warnings of a spiral coming on.
