I'm going to mention energy sorry. Mostly because this is how I understand it and what it looks like for me. Not so much taking on their emotions as much as being blasted at times by the energy that they are throwing out there.

With you, the whole chakras and energy talk annoys me, even though, that is how other people's emotions feel for me. The best thing I have been able to figure out is to minimize exposure, to take frequent breaks when possible. I often find myself using the bathroom to be able to close my eyes and just breath a bit, like trying to shake it off/out of me. I might even find myself flicking my hands like I am literally trying to expel or release it from me. It doesn't take away it completely, it does bring it down some. I can get this feeling from all kinds of emotions, even when people are overly excited (happy). It can be exhausting and difficult for me not to get sucked in.

There is some of the reminding myself that it is not mine - it is theirs. And sometimes I'm able to find a neutral peaceful stance around it, at which point I'm almost stoic in the face of turmoil. It is as if I am the calm parent to a toddlers tantrum. That's not to say the other person is having a tantrum. For me it's the energy that is being thrown off is as powerful as a tantrum. I think I do this best when I can clearly stay in the place that none of it is about me, and I'm not taking any of it personal.

Not sure if this is helpful and tbh, I'm still trying to figure out a better way of handling it overall.
