If somebody left you, you have to realize their part in your story is over. If they walked away, then you don’t need them. If God allowed it, then that means they’re not a part of your destiny.
You gotta believe in yourself more than the chatter around you. The opinions of others doesn't define you. Because in reality they don't know! You define your value. Keep working and smiling and proving your supporters right. The best is yet to come!
