Confession: I briefly worked as a "medium" for people because my emotional empathy is so sensitive. But it's not cognitive at all. I don't know why people feel the way they do. I don't even know where their emotions end and mine begin half the time (and particularly when "reading" people's "energy"). I just have a knack for describing an emotional situation as an image. People would say, "Yes, that's exactly how I feel!"
I quit that line of work for several reasons, a few being that (1) I never felt "magical" and my clients wanted me to—thereby disempowering themselves and inappropriately hyper-powering me, (2) I don't find the field to be ethical (I don't know any mediums who are trained as therapists, but they ought to be, since people are coming to them with real issues that need real treatment). And (3), I was so overloaded with "other people's vibes" that I could barely function. It became difficult to not space out all the time. I'd forget to eat, lose track of time, and so on.
For a while I thought I must be psychic. Interestingly, when I went into treatment for trauma, my sensitivity lessened. I don't know what sensitivities will come up when I do become a practicing therapist, but at least I'll have training in ethical and effective practices.
