I did not get through my problems without the help of friends, family, some amazing organisations, my brilliant case officers and the new laws in 2012- passed to protect people.
Know your rights and if you are worried call the police, domestic violence and stalking is taken very seriously and you will be listened to.
Have a look at the laws passed in late 2012- these laws helped me get some justice against M- http://www.cps.gov.uk/legal/s_to_u/stalking_and_harassment/#a02b
There are agencies set up so that you can contact them in confidence for support and advice- http://paladinservice.co.uk/

Don’t be afraid to reach out for help, it is there.
