I've never used an actual mood chart, either. back when I knew a lady called shirley, she used her own scale to tell how she wwas feeling (she'd just write the date in an note pad file, the the number on the scale) 1 being terrible, bad, 10 being the best.

I just adapt and do a version of that (I posted what I do in another thread, I believe)

I think a real mood chart would be useful though. my issue would be sticking to it

even with what I do now, I only fill it in " when I can be bothered", which lately seems hardly ever
