Well you would first need to explore what caused it in the first place. For example, maybe you have abandonment trauma from your childhood because your parents divorced. You may avoid attachment in order to protect yourself; you cant be abandoned if you don't form connections or if you abandon them first (just a common example not saying this is what you have). There is no easy fix. Regardless, trauma-informed therapy with a therapist that uses cognitive behavioral therapy would be best and safest route to address these issues, help you understand the why, and possibly move on.
Well the start is always with recognizing the problem, which you will have. I used to be an avoidant (disorganized). It's facing my parental issues over and over again and going against my avoidant tendancies. Affirmations may help too. Hope you have a good recovery, avoidant one is the easier part to heal than the anxious side :') At least for me

Guys, how to overcome avoident attachment? Its exactly as the title says. I genuinely try to overcome this and get close to men, but everytime i either get the ick and all other "avoident attachment symptoms" or the guy is a total idiot Its rlly a problem. But i am too stubborn to look for a Therapist tho and refuse.
