tt - thank you for those personal definitions, along with the fine shadings of difference between the two. I've mixed them up, the same way you have, in the past. And I've also begun to experience what a huge difference there is in perception of how things look, what is possible going forward, and how much more stable and giving the experience of empathy instead of sympathy is.
This is one mix-up, I have a clear memory of having come from my mother. I remember being literally told that empathy was how you described sympathy... that this is what it "should" be. The first time this started to get straightened out for me, was in T. Not sure how/why my mom didn't understand... but it has something to do with her PD; there was literally no evil intent behind it... perhaps only an unconscious "need" she was trying to satisfy any way she could, without regard to how it affected others.
I have a lot of "mix-ups" like this that became solidified in my neural nets... as "me". I'm really tempted to simply "shake things up" like dice in a cup and roll... and see what comes out next time. I won't though; not this time. This time, I'm taking those mix-ups apart one at a time... and making an intentional, conscious choice instead. To my surprise, that's dredging up all kinds of old yuck that I thought I was done with... and it's having a physical impact on my body again. Sure, it's a chance to study & observe & decode and reprogram... but damn it, pain is still pain and it HURTS.
Case in point - serious "war" going on with mom & SIL over remodeling plans at their place. Mom has been trying to drag me into it and I've tried redirecting her, getting her to understand some of the logic of the decisions being and the insanity of some of mom's plans & wants, and basically just letting her vent... until I really didn't want to hear the same old, same old anymore. So I started screening her calls again. Not answering. Did talk to SIL - and attempted to talk to bro - about mom's latest escape plan... but bro won't talk to me. SIL, I was able to support without getting "involved" in decisions... made her laugh a couple times and lowered her frustration/anger level... but then I realized I was back in "peacemaker" mode again.
The minute I "compromise" my boundaries, because I think I can help - or want to - don't you know, my shoulder and arm have started to hurt like the dickens again? And absolutely nothing relieves it... except shifting my focus of attention away from that drama to almost anything else. I'd really like to sort out and correct this kind of mixup - the one that has a physical result! I guess I should be glad, that I have such an unavoidable "alarm" system like this... grateful, you know? Sort of like those new cars that detect a stopped vehicle ahead... and automatically put on the brakes without conscious effort of the driver.
