This is life there must be things we don't expect to happen. Not all plans that we plan will go according to what we want. We must understand that when there is happiness, there must be deep sadness. Sometimes we will definitely find a condition where we feel lonely.
Maybe you are already very tired and stressed out about life problems that are draining your mind and physical every day. By being alone for a while, it is hoped that you will be able to release all the burdens and sadness that will make the mind more refreshed.
