Coping with Rejection Sensitive Dysphoria

I did CBT for a long time for generalized anxiety and the skills I learned there help with this as well. Things like reframing thoughts, naming my cognitive distortions, and such. It's especially useful for me to think through the likelihood of the conclusion I'm imagining. Like the reaaaaaaal and true likelihood. For example, common lies I want to tell myself is I'm stupid and lazy. Thus, my rejection sensitivity often goes to these areas too. This person heard me say a word wrong and corrected me. They think I'm stupid now and they no longer respect me or have interest in being around me. I stop and challenge the thought. Do they think I'm stupid? What evidence do I have of that? What evidence do I have that they think I'm smart? I go through the evidence that my SO loves me many, many times on any given day. I talk myself through not adding normal events to the "evidence" that he does not (disagreeing or arguing is normal between people who love each other for example) Going through it doesn't mean I won't have to again, but it does became easier and quicker for me to pull up and go through my, "no that's not accurate because..." list
