Crosstweed just want to say I've been there, and I know exactly how it feels. It hurts, a lot. On the occasions when I've gone through situations like this, honestly I didn't deal with it well, however luckily, I wasn't on my own. God was there. However I'm pretty stubborn and was resistant to give him my pain, let go, and move on. Don't be stubborn like me...
The two things that helped me were 1. Trusting in God that He has a plan, a better plan than mine. He knows and forsees everything. Also, I prayed "Thy will be done". Because, generally, I like my will being done. 2. Time. Time does heal. Not like God, but still, it helps. God bless!
