Pray...
One way to recieve strength for this is to pray. Have faith. It truely does help. Sometimes I feel so damn angry for no reason at all. Like I got this evil thing taking over my mind. I deal with this by trying to remain positive and fight those demons that keep trying to creep up on me. I know with the Lord in my life, those demons don't stand a chance. But the key word here is FAITH! Strength and understanding from your family also goes a long way!
Best of luck to you!!:praying
