Fear of losing a family member or friend?

Fear of losing a friend is the worst of all fears ,a person becomes anxious,cant sleep,cries and sometimes even thing that the other person is doing something that they might not or that soon the person might be replaced best thing sometimes is to do absolutely nothing.The fear of losing needs to be overcome.so we need to let this person go in order to overcome our fear.because only by going to the rolleacoster we will become less and less afraid of roller coasters.If the friend is meant to be lost then we will lose this friend,no matter the amount of calling,texting,or messenging.the best remedy is to wait until the other person decides to care for us,and if she/he doesnt,then forget him/her.we deserve a better person!!!
