Worship
When anger and hate are so big, you have to do cooling down. One way is to run worship.
For those of you who are Muslims can directly take wudlu and do sunnat prayers two rak'ahs. For non-Muslims directly worship according to religion and belief.
By doing worship, the heart will feel more calm. Devote all that you feel to the Creator.
This is also one of the therapies for you that may be difficult to tell others because of the element of great distrust.
Worshiping will also open your heart to be more willing to accept the situation. Convince you that there must be a wisdom behind all the hurt you experience.
