You will have to take counter actions. When Satan attacked me, I got my bible and prayed. Pray that I may declare it fearlessly, as I should. Let us see how the Word of God defines what a friend is. A friend loves in good times and in bad times.
Some friends play at friendship but a true friend sticks closer than one's nearest kin.
I believe the ultimate example of true friendship existed between David and Jonathan. Jonathan, a son of King Saul, had successfully fought many battles. And Jonathan made a covenant with David because he loved him as himself. Jonathan took off the robe he was wearing and gave it to David, along with his tunic, and even his sword, his bow and his belt. This covenant lasted a lifetime.
