As others have suggested finding a good therapist is a great first step. Specifically when it comes to early childhood trauma it might help to find a therapist trained in EMDR which is a technique that focuses on helping you overcome this behavior that feels natural. Something to note: you may not get along with your first therapist, it's honestly very similar to any personal relationship you have, if that's the case, it's totally fine to let them know it's not working out and find someone else. BUT: don't make that decision after your first meeting, especially if you've never tried therapy before you're gonna find it weird and off putting, if you can power through that and you still find you're not gelling with the therapist that's when it's ok to pull the plug.
