Been struggling with my anger because a person in a higher position than others is misusing their authority and has betrayed me personally. I've went over every possible scenario of what to do to her but forgiving and using my head and not my fists seems to be the best solution here's what I posted on her page instead of calling or going over and being combative...It took alot out of me but I've been less angry since. Jesus Christ is the key to all pain, misery, ache, and for most...forgiveness.
