Toxic Memories

I have just invented a new term and called it “toxic memories”. I defined it as “memories from your past you stick to, both good and bad”. Those which stop you living your present life. It happens because of something in the past was so good and you believe your new experiences could neither repeat nor beat it. On the other end, you might try to get rid of something not very pleasant or be afraid of something terrible that could happen again.

After some googling I found the term does exist. It’s meaning almost matches the one I had in mind. The only difference is most people define “toxic memories” as bad memories. Why do they ignore good ones? Is it not obvious that good ones could be even more harmful to your life?

What would you say about this?
