Yes..
I strongly believe that events ..traumas will set another path as a child/person struggles to work through greif/loss...Loss can be loss of their dream..
It can make a person sad translated to being mad...with anger.
Just like love can be so passionate it makes a person crazy at the early stage of connectiong..loosing someone/something could set the scene for most any anti social actions.Those who turn things inward hurt themselves (and those who love them)and then another set of grief and loss starts.
But all is not lost...the arts...hobbies being made to feel that a person matters can heal..as does any bond with another..pet/community/church even here on the site Dotsie started.
Yet even here we may bring past sorrow so complicated that it be unresolved.Others in any group can be blind to their own vulnerability and not "see" how words can hurt another person.
No one woman on this site has all the answers...but together we may be able to help.External input by face to face connection is important.Be that in a shop or with a friend.
Wording carefully how we speak to another in any group is important..

Your second point Eagle...reading about the old days..this is a gauge to your feelings.Your brain knows your pain.
I get upset at things I read everywhere..in books/paper and hear on radio..
There is no need to stop mentioning your sorrow or your loved brother..Never feel that.
Lots for me to think about from your post..wish we could walk the wee roads here..laugh and cry and hug.
take care...
