We can't trust our emotions - especially in the beginning, and for most of us for much longer than that. Emotions and feelings come from ANTs, right, whether we know it or not. Often we don't know it. We've lived so long with these ANTs that they just seem to be there, just seem to feel right. We don't even question them. So, don't trust them. If you can notice them, as you have, we must apply the same catching, labeling, and telling ourselves the truth method.
I think, for some of us, these deeper definitions or ingrained phrases we have for ourselves are core to the problem of SA. They run counter to self acceptance. "I hate myself. I'm a loser. I'm an idiot. I'm an XYZ." Whatever that core definition you have for yourself, that's deep down inside you. We may begin to use the techniques of therapy. We may begin to use slow talk well. We may begin to feel better about behavioral achievements or public speaking or mingling. All this may be true, and we are becoming more rational. And I have noticed that people still have that definition of themselves buried in there that fights to be heard, that hangs on.
It might feel like a harder belief to change. It might feel like a different side to this. But, it's still an ANT. I think that's how we should look at those definitions of self. Catch them, label them, tell yourself the truth. Turn the tables on that slowly, and that definition, too, will change to a healthy rational new definition of yourself which is accurate, real, and allow you to move forward in the right direction, allow you to continue to meet future challenges of life in a way we all deserve to be able to.
