I guess it all comes down to finding new functional ways to express yourself instead of the dysfunctional ones that we learned from our parents. I am not good at asking for what i need.
You got it!

Believe me, I know what you're going through. I've caught myself wanting to give DH the silent treatment, and I gave my roommate the silent treatment a few times when we were in college. It's something that bothers me now... .it really was a poor coping mechanism, but it was the only way I knew to resolve conflict. That's not something I'm proud of, but it's something that I have worked on, and have developed better coping skills. At the same time, I'm also working on forgiving myself--while my behavior wasn't stellar, I have to let go of that guilt, make amends with the people I hurt, and move on in a healthier way.
You are aware of your fleas, which is awesome. That's how you move on and heal, by being honest with yourself and working on the areas that bother you. You are strong. Keep going!
