What a sweet lady. I think that some people get unsure how to process those down days and panic. It's a shame. As I grow older I have learnt that those days never last (if you seek help or a good listener if it gets really tough). Maybe being a creative person (art and writing) has helped me to realise too that those down days are often a font of creativity as the mind seeks answers. So yes, there is a reason for feeling down... it's not as pointless as most people think. The tricky thing is to know when to seek support... and to find the right kind of aupport.
