Wish I could take your hands, look into your eyes and tell you, "Stay the course. Keep the faith. Trust yourself." It is very, very hard for you, no doubt about it. Feel for you. It is stunning how some of us must learn the toughest lessons right at home, right amidst the supposed nearest and dearest, the "loved ones."
But, you know, those lessons are priceless and will work for you in your life. You learn that some of the worst traits of humans are jealousy, selfishness, greed, indifference. And the best is the desire to learn and grow and develop the spark of good that is in you. Keep that spark alive and it will serve you well.
