It's definitely a thing - I've felt very much like you describe. My interpersonal relationships have always been intense, & I've overanalysed them all in such depth, I now overthink things in current interactions. Constantly having it at the forefront of my mind, that I mustn't make the same mistakes again, sometimes causes me to become a self-fulfilling prophecy, & I wonder why I even bothered. For awhile, I lived my life with the motto, 'If you can't win, don't try.' It was a pretty cruddy motto. I've managed to move beyond that mentality in some areas, but still struggle with relationships - I'm so lonely sometimes, but I just can't risk the heartbreak of starting friendships only to lose them in the end.
