emotionally abusive relationship?

Does anybody have any advice for getting over an emotionally abusive relationship? 
I left 3 weeks ago and I'm really struggling to get myself together, I know I will need time but I feel like I've got nothing. My daughter is 7 months old and although he promised to still come and visit her he hasn't. I'm glad he hasn't in one way because it means I don't have to see him and drag up the awful feelings and how scared of him I am but it's not fair for our daughter. He made me feel so bad about myself I now have no confidence and blame myself for everything. I am so different to who I used to be before our relationship and I can't even remember what it feels like to be happy and care free. I now feel scared and anxious about everything. I just don't know what to do with myself. Any advice will be appreciated if you've been through a similar situation.. TIA.
