This happened to me just yesterday. I met my childhood friend after many years and we talked for hours. During this time, I ended up venting out all of the things that get me triggered and ended up revealing personal stuff about my family to her. Although the friend is a good person and I trust her to a certain degree, I feel guilty about revealing things about my brother & sis-in-law which would change people's opinion about them. You see, my mother portrays them as loving people who are amazing, which is very far from the reality. But now I'm afraid that the friend would tell her parents etc. about what I said in the heat of the moment. I have no one to talk to. There is no support system who would only listen to me without arguing or blaming me for every single thing. So I had been bottling things for a very long time and ended up spilling them out to the friend. I feel guilty and unsure now because I generally never talk about my feelings to people who are not mom. Usually I'm extremely cautious and careful but this time I let my guard down. I never let my guard down in front of people. I used to do that in front of my mom, but that has only hurt our relationship. I hope there are no consequences for this slip up. It's a very unusual thing for me to talk about things to people. I wonder why I'm still so naïve and go back to my childish habit of oversharing things like I used to do when I was a kid. When am I gonna grow up? Why do I self sabotage?
