Make your request known to God with Thanksgiving, study God's word always to counter negative thoughts and fears.
Always remember his faithfulness to you by recalling how he has cared for you and how much more he values you. Trust God because he also can take away your suffering and make you whole. Be honest about your feelings, even if you are ashamed of it, and don't be afraid to ask for help from people.
Always have it in mind that suffering is not a sign of failure. Don't stop moving even when it feels difficult because action can provide relief. God doesn't fail, he will surely see you through your fear, he will protect you and guide you if you surrender it all to him.
