Hope is a really powerful thing. Faith is a powerful thing. These things are more powerful then your pain. Allowing your circumstances to control you leads to a path of destruction. There are still days I can't get out of bed and face reality. It's not easy but everyday you have to choose happiness. This life that brings you pain is only temporary. The pain shapes us and makes us stronger.
Remind yourself you're loved. God is more powerful then any suffering you experience. Don't let your past or present have any more control over you. I'm done giving my father any power over me. He will not ruin my life. I won't give into the pain but rather allow it to make me a better person.
