Learning to accept your situation will help you develop a sense of empowerment over the unknown. You may not know, for example, what the future holds, but being present and focusing on what you can do today, gives you control over your future decisions. In addition, trying to run, avoid, or distance yourself from fear, only transforms it into a bigger monster.
Meditate, talk to friends, family or a counselor, and express yourself through art, exercise, and spirituality and in those activities, you will find the space to express not repress your emotions. Then with time, patience and self-compassion, you will eventually find acceptance in your situation.
