I myself have been in situations where I felt hurt, troubled, or overreacted to something because it touched a nerve with what I was still dealing with because of a wound I received in the past. In these situations I have attempted to reason through the situation as objectively as I can with much prayer and introspection so I would not say or do anything damaging to another person or myself.
It really hurts to revisit my past. I just need to forgive myself to be released and restored to freedom. I shouldn’t feel a sense of guilt for a majority of the things I have done because they led me to where I am today.
