Effects of Anxiety on Memories of Past

Hi all, I just had a general question out of curiosity,

What kind of effects does anxiety & OCD have on memories of certain events in someone's past that might affecting them negatively in the present day ?

I'm currently dealing with regret and shame of a past memory over 10 years ago and I'm worried my anxiety / OCD might be twisting it into something much more then it is ?

Thanks all for any insight you might have

Stress related illnesses and diseases are well-documented. You either deal with the stress or it will deal with you. Hypertension, addictions and cardio-pulmonary issues can be chronic, progressive and fatal. It can keep us from being the type of person that we want to be.
There are ways to reduce stress. Resolve the causes and it reduces the effects. Make peace with the past.
It may never be forgotten, but it may be explained, forgiven and put to rest. Asking for help is a sign of strength.
Best of luck to you.
