It's good and healthy to identify the things weighing on our heart, and commit to working through the painful stuff to experience healing.
What's the next step? The best thing is to admit our pain to God. It could be that once we've acknowledged what's going on inside of us and taken it to him, we feel immediate closure. Often, all we need to 'get over' something is to face it and bring it to God in prayer. God has a way of calming our storms in a moment.
But sometimes he requires us to go deeper to heal our pain. We may need the help and support of others - a trusted, older friend, a pastor, a teacher, a parent. When the hurt goes deep, sometimes the wisdom and perspective of others is just what we need to bring restoration. But then sometimes God knows that our healing will only be complete once we've talked to the person/people/organisation we have the issue with, and told them how we are hurting. God's heart is to bring healing to all people, and it may just be that us confronting the source of our pain is meant to heal them too.
So what now? While you're going through your pain, it is necessary to keep looking outside of yourself. Taking the focus of yourself gives perspective too. If you find yourself in a coffee shop, ask the person next in the queue what coffee they'd like and pay for it. If you don't have the cash to do that, strike up a conversation with them instead. Dare you.
