When the moment you're in or your current situation does not bring good feelings, look up.
You have to choose to look up instead of looking at what's happening in front of and around you. It is definitely a choice you have to make and the sooner you make it, the sooner you are on your way to recovering your joy, your peace and the strength to love the people in front of you. (What about loving myself you ask? You did that when you successfully made the choice to turn to God's open arms!)
There are many, but one way I do this is with music that glorifies God by specifically calling out what Jesus has done for me. I stay there as long as I need to - focusing my attention on Jesus and off of whatever is bothering me. At times, this leads to quality time in the Father's presence, where I can talk to Him freely, tell Him how I feel honestly and He takes the heaviness from me - Hallelujah! He takes my heaviness and gives me my smile back, gives me peace, comfort and the feeling that I can go on being a light and glorifying Him with my thoughts, my words and my actions!
Here are some songs that help me and, maybe, can help you too.
