Some experiences in life are not worth to remember but the more you're trying to forget and trying to heal those the more they become vivid in your mind. Sometimes, those thoughts feel you not worthy. But, who are worthy anyway? Thus, you feel weaken with those thoughts from your experience to be desperate, not acceptable so no longer lovable, no worth at all.
But, have you tried to see those experiences as "package" just as life is like two sides of the coin; good and bad, conflict and reconciliation, damage and forgiving, joy and sadness, happiness and sorrow, health and sickness, night and day, straight line and curve line, ugly and beauty, young and old, to be born and to die?

Those are life's given human condition. It's an unending story of life. One can not do anything with those changes but you are not supposed to be stuck with the side which could ruin your life. I suggest one should embrace true "humility" which is anchored with "acceptance." However, its hard to accept if one doesn't look love at love which the Source has been given.
