At some point you wake up and realize that this is life. Things just are and things just happen. The rhyme and the reason given to you honestly fixes nothing. There are no reprisals, no redos, no corrections made to the past, and for sure no true get backs.
The damage done is damage done. No therapist, self help book, or medication can undo the memories you carry long after they “treat” your depression. Once certain things become visible in others or the true intentions of those in charge are brought to light. You can not continue on naively.
