There are times in everyone's life when things just seem to be overwhelming. Often the timing or the adversity of events increase our stress level to maximum tolerance. This is the time when we grow!
First it's important to discern what if any of those events you actually have control over. If it's outside your circle of concern, leave it to those closer to the issue who can have a direct impact upon the outcome. Trying to impose your will on something you have no influence over is akin to trying to stop the tide from flowing. nothing you say or do will change the outcome. So trust in God, and do what smart people do, pray for a righteous outcome. I've often seen those bumper stickers that announce that God is their co-pilot. Here's the truth, if God is your co-pilot, your in the wrong seat, and seriously self deceived.
Now if your cause of stress is something you do have a say so in, the answer isn't much different, pray! Pray for the wisdom to learn the lesson from the teaching moment God has placed in your life to aid you in personal growth. Ask the Lord, what are you trying to teach me here? Those lessons come in all shapes and sizes, but they are there by design. Nothing is ever so overwhelming that some time on your knees and personal reflection won't reveal the answer to. And trust me, the lesson will be repeated until the lesson is learned, so do yourself a favor and become a quick student.
