Be smart enough to know when to stand up for yourself and others. Don't let anyone walk all over you. People think they can play with fire and not get burned but everyone suffers the consequences of their actions eventually, just remember that.
People with CPTSD are often challenged when trying to maintain boundaries. Usually they grew up where boundaries were not respected. The ability to maintain boundaries can help facilitate healthy relationship and safety.
Once you set healthy Boundaries you are on your way to not only healing, but insuring that your life going forward will be Narcissist Free. So many of us were so clueless to what a boundary even was, LET ALONE SET ONE. - Mary A. Faher/THE CEMENT BENCH.
