When you grow up in a dysfunctional home it is bad to be vulnerable. You are in a different situation now and you are an adult and now you can protect yourself so you can allow yourself to be vulnerable in certain situations. This is definitely a learning process. I so agree with Puzzclar. You need to keep moving forward. You can learn that it is okay to be vulnerable in certain situations and therapy is one of those. It is not normal to never be vulnerable. You can learn all you need to about this by continuing to move forward.
