For those who witnessed or lost loved ones during other terror attacks Friday's killings on London Bridge are another painful reminder of their broken lives.
Brendan Cox, the husband of murdered MP Jo Cox, is one of more than 70 people affected by terror who has signed a letter demanding change and more support for those left behind.
When you hear there's been another attack you have an immediate travel back in time to your own experience to when you were told your own loved one was caught up in their own attack.
In Brendan Cox's own words, the worst thing that could have happened to him has happened. In 2016 his wife was murdered in her constituency.
What we as survivors want to make sure is that we learn the lessons both to make sure these things happen less often in the future but also so that those people who are bereaved, the people that been injured and are recovering that they get the support that they deserve. The problem is at the moment that simply isn't the case. There are too many families from Westminster, London Bridge from the other attacks that have been in London the last few years who are still on waiting lists for mental health support who compensation hasn't come through for who feel that they have been neglected.
In a letter signed by more than 70 victims of terror attacks they have called for the creation of a 'Survivor's Charter' with better support for victims and a security plan in all public spaces.
If we aren't supporting people who are attacked and injured in terror attacks then what message does that send to people who are considering carrying out these incidents?
The grieving parents of London Bridge victim from two years go, Sara Zelenak, expressed their frustration of enduring a long inquest and authorities not learning from their daughter's death.
Suffering and painful for us victims to do this ten week inquest and then they make no change. And they waste all that money for what? What have they achieved? If they don't make any change - they let him out early and he does it again. We're all unsafe - we've got massive holes in our hearts that can never be healed.
Survivors of terror have been through the worst and all victims deserve all the support they can get.
