Anniversaries
When a loved one has died, the anniversary of their death can bring back the awful feelings you had at the time. The same can happen on the anniversary of a major incident. The brain is clever at recognising things that will help you remember.
Like if the disaster happened in the autumn, perhaps the leaves falling and darker nights will trigger the difficult feelings again without you realising why.

Sometimes there will be things on the news or social media in the build up to the anniversary. It can be a good idea to avoid watching TV or using social media around this time if you think it will be upsetting.
It’s good to plan what you will do on the anniversary, especially the first one. But, there is no correct thing to do, it can be whatever you want.
