In the Bible Abramhan and Sarah did the very same thing, and it just about cost them their lives and the lives of the nation of Egypt.
They were living in their promised land, doing the will of God, and then famine hit the Canaan land area. So instead of walking by faith and not by sight they picked up their bags and belongings and headed down to Egypt, which wasn't hit by famine. Egypt in scripture seems to have always been a type or allegory of sin or living in this world, and not in the Kingdom of Heaven; a type of worldliness, wickedness, ungodliness and so on. So, Abraham and Sarah left their promise, and went away from God's will to let the "world" and the pleasures of sin take care of their needs for the time being!
It is never appropriate to let this world supply our needs and pleasures no matter how short we say that we will stay! If we trust in Jesus and rely on his Word, staying true to his promises, commands and obey, then he will make sure the "people of this world" will take care of us!
While in Egypt Abraham was scared that he was going to die for the sake of Sarah his wife, because she was so beautiful! There is one reason NOT to go to Egypt if you ask me! So, they said that Sarah was his sister, and Pharaoh almost married her! God had to step in and just about destroy Egypt with a plague so that Abraham and Sarah would get back to His promise and will!
It never pays to leave the will of God just to sooth your pain and anguish! Jesus died on the cross for that very reason! We must learn to completely trust in Jesus for everything in our lives! Does that mean do nothing, and just sit around and wait? NO! NO! NO!
Jesus told us to obey his commandments, and to occupy until he comes! We must work, but we must work and pray will doing God's will and commandments, and living within the promises that he has given us! Each one of us probably has a different promise that God wants us to fulfill, and each one of us is unique in the sight of God, so we must not let what others are doing turn us aside from our spiritual promise!
Let us be like Joseph, who endured through the hardships, distresses, pain, anguish and loss so that he could fulfill God's will even though he couldn't see where God was going to take him! Joseph went from Daddy's favorite and God's little dreamer to a hurt, bruised boy at the bottom of a pit. He went from a pit to slavery. From slavery to seduction. From seduction to prison. From prison to dreams. From dreams to being the President of Egypt! Even in death Joseph was still living in God's promise and will by requesting to have his bones taken from Egypt and buried in the land that God had promised the nation of Israel!
Stick with Jesus he will see you through!
Yours through the famine,
