It is anger about the injustice of life that your mother presented to you in your formative years, and that anger has been formed in your many neuropathways.

 anger at the injustice of being unlucky while other people are lucky.

there is a yet to be resolved issue- injustice. And anger fuels the search for justice.

Can you define luck as you understood it from early on, in a stream of consciousness way, maybe?

The above bolded, I have my work cut out for me.  Resolving the issue that remains.  I will go with a stream of consciousness now..

Luck is to be happy, to have good people in life, and to be able to enjoy.  It is to not be lonely and to have caring authentic people that support you.  Luck is having things be light, not heavy.  Luck being that everything isn’t so hard, it means you wake up and live your life and you are happy as is, it isn’t a struggle.  luck is just being yourself and being fine with it, and everything else around also falls into place
