Old boy, you just have to be full of prayers. If u believe that there is nothing God cannot do; it is time for you to wake up and put the enemies to shame. I pray that God will help you.
Again, you need to examine yourself if you're not the root of your own problem. Think about making things work instead of quitting. I know it is not easy, but the Lord will give u the strenght to cope and make things right. Good Luck!
