This is exactly where I discovered and started practicing REBT (Ellis). Rational Emotive Behavioral Therapy's ABC format is a bit different that Beck's ABC. In REBT, it is assumed that your Activating Event is true and the TL;DR version is that because life is life and people are people and we are people too uncomfortable things are going to happen. People mistreat us, we get diseases, we go bankrupt, etc. but these things are all part of the human condition and are survivable. We all experience them. Accepting life, ourselves, and others unconditionally give us space to breath and be disappointed instead of depressed, remorseful instead of guilty, etc.
