It is easy to feel broken around these kind of things, and I think for a lot of us with insecure attachment styles there are core beliefs that align with that thought (for instance, without being aware of it for a long time, I have a core would about being unlovable). Some good news is that it's possible to work on and start healing, and there are a lot of resources available to help that didn't used to exist - some good youtube channels, subreddits, therapy, etc. I've been working on my attachment style for the last couple of years and I've still got plenty of distance to go but I have noticed big positive changes in my life from the work I have been doing.
