I've always had a hard time knowing whether I've gotten over a traumatic event, or if I've just repressed the memories/emotions related to it. My parents got divorced back in 2009, and I thought I've been over it for years, but I recently noticed that I start to cry when I think about it. Is this a normal thing? Is it possible to cry about something you've already come to terms with?

I guess the main question I have is how do you know when you've gotten over something? Is there a sign you recognise, or do you just feel it? Is it something you can just never know for sure?
