P -- Pray. Sit in meditation, repeat the same prayer over and over, listen for answers and talk to God. There's a wonderful book about the power of mantra prayer call The Way of the Pilgrim.
R -- Resist negativity. Force yourself to avoid the downward spiral of feeling lost in a sea of negativity. Wear a rubber band around your wrist, and every time you think or say a negative word about yourself and your situation, snap the rubber band. Paste positive affirmation in your bathroom, kitchen and bedroom so you'll be reminded of the positivity that awaits you. Create an affirmation for yourself that you repeat daily for at least 10 minutes such as, "All is well in my world." Or "I am healthy, wealthy, loved and loving."
A -- Ask for help. The only way to get through tough times is by asking for help -- from your higher power, from your loved ones on the other side, from your angels and guides and from your friends and family here.
Y -- Yield to your higher power. Sometimes life just stinks. Period. And there's no rhyme or reason for it that we can discern. Part of the key to finding happiness to life is learning to surrender to these tough times. Once we can accept the grief that we're dealing with in the present time -- whether it's over the loss of a loved one, the loss of a job, or the all consuming loss of hope -- we can begin to build our way back to ourselves.
