Whenever I come across difficult people, I think about what kind of crap I’ve had to put up with since BD and I say to myself, if I could survive through all of that, there’s nothing else I can’t push through!!
I had a similar experience - after surviving the loss of my 24 year marriage after many years of fearing that outcome, I was pretty much freed of fear. Dating breakup? Small potatoes compared to my divorce. Performing onstage? I really didn’t care what anybody thought of me anymore. Difficult people? I had the skills to DB them and not take it personally. It’s very freeing if you’ve don’t the work and can embrace the lessons! Good for you!
