Dare I ask, are you really an empath - or are you someone who sees off tones and push offs in the most innocent remark?
I had an uncle who could see negative remarks and put downs in the most innocent of remarks. It made conversation very difficult.
I have also, myself, assumed someone was saying something upsetting to me,when, when I went back over the message later realised I had got it completely wrong.
I do wonder how far someone like the OP is an empath, and how much someone who suffers from lack of self-esteem and sees put downs and negative attitudes in what other people do or say, or messages, because that is what their lack of self esteem leads them to expect. Were they to assume that there is no reason why anyone should put them down, therefore any supposedly off message is the result of them choosing to interpete the message that way, life would be much better and yhey would discover thta they were not as empathetic as they think.
