Not sure what to do or think anymore??

Hi, I have just joined this site after speaking with my social worker today at a very low point in my life for the last year and a half. I recently left a very serious domestic voilent marriage (19 years), I have two children, and only one lives with me after I kicked my oldest out for also hitting me after I left my now ex husband. My ex was very abusive to where he would hit me, throw me up against walls, threaten me with knives and to cut my throat, rape me, and emotionally, physically and mentally control me to what I wore, how I had my hair cut and coloured and where I went and with who. Since leaving him a year and a half ago the controlling hasn't stopped, neither has the abusive text messages, but him hitting me has as I am no longer in his house for him to fully control me.I have had to learn to cope on my own and have been told by my physcoligist and phyciatrist that I have Clinical PTSD, Agraphobia, Aniexty, Depression, and suffer from not being able to leave my own home to complete my daily tasks as I am scared of running into him (he lives 10 - 15mins away). I am wanting to leave Brisbane and move up North to where I will feel safer then I do at present with living so close to him and him being able to spy on me and watch my house ... I am not sure where to go or who to turn to for advice, and because none of my family know the real reasoning why we parted and went out seperate ways I feel like I can't talk to them, because if they find out what my ex did to me and put me through for so long I am scared they will think negitive things about me.
