Oh Mejo ((hugs))
Do not feel embarrassed. The last time my XABF abused me, when I finally pressed charges, I had a black eye and was limping from tumbling down the stairs.
Like you I was very embarrassed to go to work but I found that my boss and coworkers were very supportive. My boss even insisted that I stay with her for a couple of days just in case he decided to come to my place after being released from jail.
The shame is
his not yours.
There were none for me back then and I had to deal with the legal aspects alone but call the court house and find out if they have a victim's advocate. Also call your local DV hotline, they probably will have some resources and f2f support available for you.
