Four noble truths of the Buddha, 1. Life is suffering,   2. The truth of suffering,   3. There is a way out of suffering,   4. The path to freedom from suffering.

Life is tough and terrible. There is so much suffering and cheating and lying and everything. A toothache is painful but the suffering is in the mind who endures the toothache longing for it to end. Everyone suffers pain and has a terrible time. But, it is those, who reach beyond the suffering to see the truth of life and the truth of Buddha nature, they live a life of love, compassion and wisdom.

There are no simple cures. And, for the Buddha, he said one is reborn. So, in time you will return in another life. And go thru similar until you have learned the lesson that is taught. Suicide is not the answer. Karma will keep you in this circle. Despair is not the answer. You may need to express your feelings and that will help for the moment. You may need to take up the practice of mindfulness, meditation. Find a teacher and sangha to learn how to break into freedom. Maybe take lessons in self-defense. Be able to feel that you take control of your life.
