One of the reasons I struggle with boundaries is that I weigh the discomfort of the current situation against the unpleasantness of being yelled/ignored/guilted after I assert myself. I don't know where I learned this weird fear, but I often think that the person might lash out. Now that I know how a loving person will act (me), I know what the outcome should be after I stop a conversation in mid-point when it's unpleasant.
Whew, I need a break because I don't have a psych degree and that was heavy! Let's take a sidebar, shall we?
I'm drinking the best drink with my breakfast miso soup... hot water and lavender leaves! It's delicious, and all I did was throw 2 fresh lavender leaves into a hot cup of water. So simple and so lovely, it reminds me of Grandma Lavender. Have a splendid day!
