No contact troubles

Hi all, been having waves of guilt, abandonment, shame since I've gone no contact with my parents and my sister. I came to the realization I had to do this to stop the narcissistic abuse in all levels since she can no longer physically abuse me or have my dad do it. I've blocked my sister too cause she would be a flying monkey as well as my father. There are days im ok. And I can venture on, but there are days, weeks that I feel sick, nauseous, and feel like crumbling, but with the grace of God I keep going. Its exhausting, and hard and at the same time I'm processing stuff that is coming up from my past. The worst tho, is when my husband doesn't understand and gets mad at me cause I'm not happy. Which makes me feel worse, but again I am learning to stand up for myself. Im not sure if I'm making sense.
