In these moments it is so important to regain control. It is in these moments that it is important to take it one day at a time. The most important thing at this time is to pause and rest. Then, instead of looking at the whole picture, just look at one area and complete one task that is more pressing without the feelings of guilt. It also means that maybe it is necessary to take a few steps back and temporally remove people and situations that are not helping but instead are draining our energy (in love of course, the once who count will understand).
For me, when I go through moments like these I tend to remember the words of Jesus after he spoke to them of some challenging times to come, encouraging His disciples with these words: "I have said these things to you so that in Me you would have peace. In the world you will have tribulation; but take heart, I have overcome the world" (John 16:33). No matter what we go through we can still have peace in Christ because He has overcome the world, even death itself!
Peace comes when our heart's focus is on the One who can help us overcome all the circumstances. Being free from worry and having peace comes from knowing this truth. As long as Jesus remains our focus, we can trust and have faith to take it one day at a time even though we don't see the outcome or have the answers. When life becomes overwhelming that is the time to strip ourselves away from all the distractions, slow down and find dwelling in His Word. When we set our feet on the Truth, the Rock - we gain balance in our life. When we stand on His truth we become free of the worries of this world.
