Any advice?😭

Does anyone have any advice or anything on how to leave a narcissist whom you dad a baby with and been together 3 years? It’s so hard each day. I’m numb I can’t do it anymore. Credit is ruined I have no money because he works and I’m a stahm. 22 and Ben through so much bullshit I just want out and anyway from him and to keep my daughter with me. We’d have to be legally separated for a year before able to divorce because of the state we got married in. I know this post is scrambled and may not make sense I’m too depressed to focus on writing lol but please any advice or tips
