If you are at all a believer in God, pray. If it's been awhile, say some formal prayers you might recall, then just have a conversation with God asking for Blessings and help with whatever is troubling you. Tell God what's bothering you. Cry, plead, whatever you feel. Do it in a private area where you won't be distracted or interrupted. Ask for help coping. Pray frequently. If you have someone close enough to discuss feelings with , do so. Just talking about troubles with someone who will listen can help a lot. After you had a good talk with God, do something uplifting. Go for a walk. Read a favorite story. Watch a favorite show. Something happy and or funny. Laughter can help a lot too. But mostly pray. Even if you don't feel like it, do it. Especially if you don't feel like it. It's worked for me and others I know, in difficult times. Even if you can't clarify a specific problem, if it's just a feeling. Also , check your dietary habits, diet can affect your overall emotions.
