Similar here. Guess mostly caused by not being fully, unconditionally, accepted as a child. But who knows, it can be whatever reason reaching from planets' position at birth to genes, character, karma, you name it. The question is: how do we deal with it as adults, if we (thankfully) finally realize that? If we know it doesn't make much sense and that it doesn't serve us? I am working on it for 10+ years and it is a tough (and not very productive 🤭) job...but step by step hopefully it will click that we are worth every breath we take, not every we task we finish...🙏
