Attachment style is one of the biggest indicators in how we will have relationships with others. There is a lot of information on what each of the four attachment styles are, but what do you actually do if you have an insecure style and want to change that? How can you actually create secure attachment?
There are a few ways we can do this: through somatic attachment therapy, soothing the nervous system (ie, walks, extreme temperature change), EMDR, and meditation. Attachment based EMDR clinicians are preferable, but if you can work with any EMDR therapist, it will be helpful.
Here are a few resources:
