Hello clouds_and_sun,

yes, I feel that other people's moods affect me as well. I would think that this is quite natural, as we are social beings and thus interact with others and also partly define ourselves through others. I don't think that it is odd in any way.

I suppose if anybody's mood can have a huge impact on you, it might get too much. I find that if I feel quite stable and have a certain sense of equanimity, I am slightly less affected by other people's moods, whereas when I am anxious I depend more on other people's approval, which also involves picking up on their moods quickly and being very much affected by them.
I'm a lot more affected by people and their moods who I see a lot like work colleagues.

I think most people would probably say that they are most affected by the moods of those people they care most about. I suppose if it's like this, it's not bad thing, as it shows that people can feel empathy and understand others and thus develop sensitivities.

I don't know whether that helps.

I hope you keep well.

Hugs from Shadow-world
