How can you best protect yourself against personal grief without affecting your ability to care for those to whom you will be providing service

Find happiness in Jesus and the people He puts in your life. The people you are giving service to have problems of their own and even happiness too. If you can look at the world with selfless eyes, seeing the people around you, then you can find joy in other people's happiness. Not saying whatever you're going through isn't going to be hard, but it helps with constat depression and going even further than that.

The best way is to swollow and hold in your breath
