having a headache and stressing out.
The 2 are probably related.
If I may, just a practical tip:
Most people are perplexed when something arises and they don't know how things will work out. But if you look back on your life, things have always worked out. Regardless of the outcome, you got through it. I know this because you are still here. And you will get through whatever is causing this stress.
The difference between those who experience peace through trials and those who experience stress has to with knowing that God will be with you in the trial and will ensure that everything will soon be ok.
I will be glad to go through the reasons why this is so if you like, but you are a child of God. Because this is true, you will be ok.
